We use Andrew Morton's 'patch-scripts' utilties -to keep the complexity of managing changes across multiple kernel targets down. -They handle the ordering metadata, application, refreshing, and removal of -patches for us. Please read scripts/docco.txt for a more thorough explanation -of what 'patch-scripts' do. - -We create a thin wrapper around patchscripts with our ./prepare_tree.sh. It -exports two environment variables. PATCHSCRIPTS is a relative path from the -kernel source tree to the checked-out patchscripts repository. It is requires -for patchscripts to operate on data outside the kernel source tree. It also -puts the absolute path to the scripts/ directory at the front of PATH. -Finally, it creates a 'series' link from the kernel tree back to the proper -series file for that kernel tree. More on that below. - -prepare_tree.sh and the patch-scripts commands are the only interface we should -use on a daily basis. We should never have to manage the patches by hand. -This will save us heart-ache once we're good with the tools. I promise. - -Data to be aware of: - -patches/ - contains all the patch files themselves. We should have a patch per - functional change. - -series/ - the text files that patch-utils use to define the ordering of patches - that are applied to a tree. We have a series file for each kernel - tree variant that requires wildly different patches. (architecture - differences, stock vs. redhat, etc) - -pc/ - control files for patch-utils. These are per tree and should never - be in cvs. - -txt/ - text descriptions of the patches. Nice, but not functionally required. - -First, before anything happens, you need to prep a tree for use with -patch-utils. This means putting a series link in the file and setting the -environment variable: - - $ eval `./prepare_tree.sh -t /tmp/kernels/linux-2.4.18 -r stock-2.4` - -prepare-tree.sh is careful to output variable assignments to stdout and -everything else to stderr so the eval won't go awry. It also is clever about -resolving the series name, so tab-completed relative paths to the series files -can be used with -r. (it assumes that series/ is under where prepare_tree.sh -was executed from). The series link that is created from the tree back into -the cvs repository is created by force.

After the patch is imported it still needs -to be applied and refreshed with 'pushpatch' and 'refpatch'. ___remember to -cvs add the patch with -ko___ so that tags in the context of the diff aren't -change by CVS, rendering the patch unusable. - -It is considered valuable to have a common HEAD which can be checked out to -patch a kernel and build lustre across lots of targets. This creates some -friction in the desire to keep a single canonical set of patches in CVS. We -solve this with the patch-utils scripts by having well-named patches that are -bound to the different series. Say alpha and ia64 kernel trees both need a -common lustre patch. Ideally they'd both have our-funcionality.patch in their -series, but perhaps the code path we want to alter is different in the trees -and not in the architecture-dependant part of the kernel. For this we'd want -our-functionality-ia64.patch in the ia64 series file, and -our-functionality-alpha.patch in the alpha. This split becomes irritating to -manage as shared changes want to be pushed to all the patches. This will be a -pain as long as the kernel's we're receiving don't share revision control -somehow. At least the patch utils make it relatively painless to 'pushpatch' -the source patch, clean up rejects, test, and 'refpatch' to generate the new -patch for that series. diff --git a/lustre/kernel_patches/config/config-linux-2.4.20-uml b/lustre/kernel_patches/config/config-linux-2.4.20-uml deleted file mode 100644 index 2d4a2d5..0000000 --- a/lustre/kernel_patches/config/config-linux-2.4.20-uml +++ /dev/null @@ -1,297 +0,0 @@ -# -# Automatically generated make config: don't edit -# -CONFIG_USERMODE=y -# CONFIG_ISA is not set -# CONFIG_SBUS is not set -# CONFIG_PCI is not set -CONFIG_UID16=y -CONFIG_RWSEM_XCHGADD_ALGORITHM=y -

They are quite powerful. They can be used on -projects other than the linux kernel. They are easy to use, and fast. - -You end up doing a ton of recompiling with these scripts, because -you're pushing and popping all the time. ccache takes away the pain of -all that. http://ccache.samba.org/ - be sure to put the cache -directory on the same fs as where you're working so that ccache can use -hardlinks. - -The key philosophical concept is that your primary output is patches. -Not ".c" files, not ".h" files. But patches. So patches are the -first-class object here. - -Installation -============ - -You place all the scripts somewhere in your path, or in -/usr/lib/patch-scripts. - -Terminology -=========== - -The patch scripts require three special directories called "pc", -"patches" and "txt". - -If the environment variable PATCHSCRIPTS is set, it is taken to to be -the directory in which those three directories reside. Typically, it -would be a relative pathname. So - - setenv PATCHSCRIPTS ./i-put-them-here - -would tell the patch scripts to look in ./i-put-them-here/pc, etc. - -If PATCHSCRIPTS is not set, and the directory ./patch-scripts is -present then the patch scripts will us ./patch-scripts/pc/, -./patch-scripts/patches/ and ./patch-scripts/txt/. - -Otherwise, the patch scripts use ./pc, ./patches and ./txt. - -In this document, the symbol $P is used to describe the directory which -holds the pc/, patches/ and txt/ directories, as determined by the -above search. - -It is expected that $P will always expand to a relative path. - -Concepts -======== - -All work occurs with a single directory tree. All commands are invoked -within the root of that tree. The scripts manage a "stack" of patches. - -Each patch is a changeset against the base tree plus the preceding patches. - -All patches are listed, in order, in the file ./series. You manage the -series file. - -Any currently-applied patches are described in the file -./applied-patches. The patch scripts manage this file. - -Each patch affects a number of files in the tree. These files are -listed in a "patch control" file. These .pc files live in the -directory $P/pc/ - -Patches are placed in the directory $P/patches/ - -Documentation for the patches is placed in $P/txt/ - -So for a particular patch "my-first-patch" the following will exist: - -- An entry "my-first-patch.patch" in ./series - -- An entry "my-first-patch" in ./applied-patches (if it's currently applied) - -- A file $P/pc/my-first-patch.pc which contains the names of the - files which my-first-patch modifies, adds or removes - -- A file $P/txt/my-first-patch.txt which contains the patch's - changelog. - -- A file $P/patches/my-first-patch.patch, which is the output of the - patch scripts. - -Operation -========= - -When a patch "my-patch" is applied with apatch, or with pushpatch -(which calls apatch), all the affected files (from $P/pc/my-patch.pc) -are copied to files with ~my-patch appended. So if $P/pc/my-patch.pc -contained - - kernel/sched.c - fs/inode.c - -then apatch will copy those files into kernel/sched.c~my-patch and -fs/inode.c~my-patch. It will then apply the patch to kernel/sched.c -and fs/inode.c - -When a diff is regenerated by refpatch (which calls mpatch), the diff -is made between kernel/sched.c and kernel/sched.c~my-patch. How do the -scripts know to use "~my-patch"? Because my-patch is the current -topmost patch. It's the last line in ./applied-patches. - -In this way, the whole thing is stackable. If you have four patches -applied, say "patch-1", "patch-2", "patch-3" and "patch-4", and if -patch-2 and patch-4 both touch kernel/sched.c then you will have: - - kernel/sched.c~patch-2 Original copy, before patch-2 - kernel/sched.c~patch-4 Copy before patch-4. Contains changes - from patch-2 - kernel/sched.c Current working copy. Contains changes - from patch-4. - -This means that your diff headers contain "~patch-name" in them, which -is convenient documentation. - -Walkthrough -=========== - -Let's start. - -Go into /usr/src/linux (or wherever) - - mkdir pc patches txt - -Now let's generate a patch - - fpatch my-patch kernel/sched.c - -OK, we've copied kernel/sched.c to kernel/sched.c~my-patch. We've -appended "my-patch" to ./applied-patches and we've put "kernel/sched.c" -into the patch control file, pc/my-patch.pc. - - Now edit kernel/sched.c a bit. - -Now we're ready to document the patch - - Now write txt/my-patch.txt - -Now generate the patch - - refpatch - -This will generate patches/my-patch.patch. Take a look. - -Now remove the patch - - poppatch - -applied-patches is now empty, and the patch is removed. - -Now let's add a file to my-patch and then generate my-second-patch: - - Add "my-patch.patch" to ./series (no blank lines in that file please) - - pushpatch - -OK, the patch is applied again. Let's add another file - - fpatch kernel/printk.c - -Note that here we gave fpatch a single argument. So rather than -opening a new patch, it adds kernel/printk.c to the existing topmost -patch. That's my-patch. - - Edit kernel/printk.c - -Refresh my-patch (you end up running refpatch a lot) - - refpatch - -Now start a second patch: - - fpatch my-second-patch kernel/sched.c - -Now take a look at applied-patches. Also do an `ls kernel/sched*'. - - Edit kernel/sched.c, to make some changes for my-second-patch - -Generate my-second-patch: - - refpatch - -Take a look in patches/my-second-patch.patch - -Don't forget to add "my-second-patch.patch" to the series file. - -And remove both patches: - - poppatch - poppatch - - -That's pretty much it, really. - - -Command reference -================= - -Generally, where any of these commands take a "patch-name", that can be -of the form txt/patch-name.txt, patch-name.pc, just patch-name or -whatever. The scripts will strip off a leading "txt/", "patches/" or -"pc/" and any trailing extension. This is so you can do - - apatch patches/a - -to conveniently use shell tabbing to select patch names. - - - -added-by-patch - - Some internal thing. - -apatch [-f] patch-name - - This is the low-level function which adds patches. It does the - copying into ~-files and updates the applied-patches file. It - applies the actual patch. - - apatch will do a patch --dry-run first and will refuse to apply the - patch if the dryrun fails. - - So when you are getting rejects you do this: - - pushpatch # This fails, due to rejects. Drat. - apatch -f patch-name # Force the patch - (or) pushpatch -f # Force the patch - - OK, you've now applied patch-name, but you have rejects. Go fix - those up and do - - refpatch - - And you're ready to move on. - -combine-series output-file - - It incrementally combinediffs all the patches in series to make a - complete patch for the series. Requires combinediff frmo patchutils. - - See http://cyberelk.net/tim/patchutils/ (Don't download the - "experimental" patchutils - it seems to only have half of the - commands in it. Go for "stable") - -cvs-take-patch - - I forget. - -export_patch - - export the patches listed in ./series to a set of files which - are named in such a way that the sort order is the same as the - order of the series file. - - Usage: export_patch directory [prefix] - - Example: - - Suppose ./series contains - - mango.patch - orange.patch - banana.patch - apple.patch - pear.patch - - export_patch ../mypatches fruit - - The patches would be copied to - - ../mypatches/p00001_fruit_mango.patch - ../mypatches/p00002_fruit_orange.patch - ../mypatches/p00003_fruit_banana.patch - ../mypatches/p00003_fruit_banana.patch - ../mypatches/p00003_fruit_banana.patch - - Named in this way, someone may easily apply them: - - cat mypatches/p*fruit* | patch -p1 - - If prefix is omitted, the patchnames will be transformed - such that "original.patch" becomes "pXXXXX_original.patch". - -fpatch [patch-name] foo.c - - If patch-name is given, fpatch will start a new patch which - modifies (or adds, or removes) the single file foo.c. It updates - ./applied-patches and creates pc/patch-name.pc. fpatch will copy - foo.c to foo.c~patch-name in preparation for edits of foo.c. - - If patch-name is not given then fpatch will add foo.c to the - current topmost patch. It will add "foo.c" to $P/pc/$(toppatch).pc. - It will copy foo.c to foo.c~$(toppatch). - -import_patch - - Imports a set of patch files, creating $P/pc, $P/txt, $P/patches and - ./series as necessary. It also creates $P/txt/*.txt by stripping - off the top of the patches (and removes any diffstat output it finds, - so that it can eat refpatch output and export_patch output.) The - imported patch names are appended to the series file. - - In creating the $P/txt/*.txt files, mail headers are stripped with - formail, preserving the "From:" and "Subject:" lines. "DESC" and - "EDESC" markers are added if they are not already present, using the - "From:" and "Subject:" lines for the DESC portion, if they are present. - (See "patchdesc" command, below, for more on these markers.) - - Also, it can rename the patch file as it is imported by stripping out - a pattern. This is useful if, as often is the case, you have patch - sets with filenames designed to help sort the patches into the correct - order, such as "p001_xxx_funky_stuff.patch" you can have it automatically - renamed to funky_stuff.patch on import, and let the series file manage - the ordering. - - Import_patch will uncompress patches (*.Z, *.bz2, *.gz) as necessary. - - Usage: - - import_patch [-p pattern] patchfile ... - - Example: - - % ls ../fruit/p*patch - ../fruit/p00001_northern_apple.patch - ../fruit/p00001_tropical_mango.patch - ../fruit/p00002_northern_pear.patch - ../fruit/p00002_tropical_orange.patch - ../fruit/p00003_tropical_banana.patch - % import_patch -p 'p[0-9]*_tropical_' ../fruit/p*tropical* - Recreated pc/mango.pc - Recreated pc/orange.pc - Recreated pc/banana.pc - % import_patch -p 'p[0-9]*_northern_' ../fruit/p*northern* - Recreated pc/apple.pc - Recreated pc/pear.pc - - Then you can "pushpatch; refpatch" 5 times. - -inpatch - - List the names of ths files which are affected by the current - topmost patch. - - This is basically - - cat pc/$(toppatch).pc - -mpatch - - A low-level thing to generate patches - -new-kernel - - Some thing I use for importing a new kernel from kernel.org - -p0-2-p1 - - Internal thing to convert patch -p0 form into patch -p1 - -patchdesc - - Generates a single-line description of a patch. - - The txt/my-patch.txt files have the following format: - - - DESC - some short description - EDESC - - The long description - - - I use - - patchdesc $(cat series) - - to generate short-form summaries of the patch series. - -patchfns - - Internal utilities - -pcpatch - - Standalone tool to generate a .pc file from a patch. - - Say someone sends you "his-patch.diff". What you do is: - - cp ~/his-patch.diff patches/his-patch.patch - pcpatch his-patch - - This generates $P/pc/his-patch.pc and you're all set. Add - "his-patch.patch" to ./series in the right place and start pushing. - -p_diff - - I forget - -poppatch - - Remove one or more patches from the current stack. This command - does *not* use the series file. It works purely against - applied-patches. - - Usage: - - poppatch - Remove the topmost patch - poppatch 10 - Remove ten patches - poppatch some-patch-name[.patch] - Remove patches until "some-patch-name" is top patch - -pstatus - - Shows status of patches - - Usage: - pstatus [patchfile ...] - - One line per patch is output showing: - 1: Patch number in the series file - 2: Whether the patch is currently applied - 3: Name of patch - 4: Status of the patch (needs pcpatch, changelog, refpatch) - - If no patchfiles are specified, $P/patches/*.patch - are assumed. - - Caveats: - A patch set which contains separate patches to add a file - and modify that same file may give spurious "Needs refpatch" - status for the patch which adds the file or the topmost patch. - -ptkdiff - - Two modes: - - ptkdiff - - - Run tkdiff against all the file affected - by $(toppatch). The diff is only for the changes made - by the top patch! ie: it's between "filename" and - "filename~toppatch-name". - - ptkdiff filename - - Just run tkdiff against that file, - showing the changes which are due to toppatch. - -pushpatch [-f] - - Apply the next patch, from the series file. - - This consults ./applied-patches to find out the top patch, then - consults ./series to find the next patch. And pushes it. - - pushpatch - - Apply the next patch - - pushpatch 10 - - Apply the next ten patches - - pushpatch some-patch-name - - Keep pushing patches until "some-patch-name" is toppatch - - pushpatch -f - - Push the next patch, ignoring rejects. - -refpatch - - regnerates the topmost patch. Reads all the affected files - from pc/$(toppatch).pc and diffs them against their tilde-files. - - Also pastes into the patch your patch documentation and - generates a diffstat summary. - -removed-by-patch - - Some thing. - -rename-patch - - CVS rename for patches. - -rolled-up-patch - - Bit of a hack. Is designed to generate a rolled-up diff of all - currently-applied patches. But it requires a ../linux-2.x.y tree to - diff against. Needs to be redone. - -rpatch - - Internal command - -split-patch - - Some thing someone write to split patches up. I don't use it. - -tag-series - - Assuming you keep pc/*, patches/* and txt/* under CVS revision - control, tag-series allows you to tag a patchset's individual - components. I use - - tag-series s2_5_44-mm3 pc/2.5.44-mm3-series - - which will attach the cvs tag "s2_5_44-mm3" to every .pc, .patch - and .txt file which is mentioned in the series file - "pc/2.5.44-mm3-series". - - It will also tag pc/2.5.44-mm3-series, which is a bit redundant - given that I use a different series file for each patchset release.. - - -toppatch - - Print the name of the topmost patch. From ./applied-patches - -touched-by-patch patch-filename - - List the names of files which are affected by a diff. - -unitdiff.py - - Rasmus Andersen's script to convert a diff into minimum-context - form. This form has a better chance of applying if you're getting - nasty rejects. But patch can and will make mistakes when fed - small-context input. - - -Work Practices -============== - -I keep the kernel tree, the $P/pc/, $P/patches/ and $P/txt/ contents under -CVS control. This is important... - -I have several "series" files. I keep these in $P/pc/foo-series and use - - ln -s pc/foo-series series - -when I'm working on foo. - -If someone sends me a patch I'll do: - - cp ~/whatever patches/his-patch.patch - pcpatch his-patch - apatch his-patch - - If apatch fails then run `apatch -f his-patch' and fix the rejects. - - refpatch - - to clean up any fuzz. - - poppatch - cvs add pc/his-patch.pc patches/his-patch.patch - cvs commit pc patches - - Now edit ./series and place "his-patch.patch" in the appropriate place. - - -If you're working on a particular patch (say, "dud-patch") and you -balls something up, just run: - - refpatch # Generate the crap patch - poppatch # Remove it all - rm patches/dud-patch.patch - cvs up patches/dud-patch.patch - -and all is well. - - -Getting updates from Linus -========================== - -What I do is to grab the latest -bk diff from -http://www.kernel.org/pub/linux/kernel/people/dwmw2/bk-2.5/ -and do: - - gzip -d < cs > patches/linus.patch - pcpatch linus - apatch linus | grep diff - - Now fix up all the files which got deleted, - because there's something wrong with bitkeeper diffs: - - cvs up -ko - - apatch linus - $EDITOR linus/linus.txt - - Add the changeset number to txt/linus.txt - - refpatch - poppatch - - Now add "linus.patch" as the first entry in your ./series file and - start pushing your other patches on top of that. - -BUGS -==== - -Tons and tons. The scripts are fragile, the error handling is ungraceful and -if you do something silly you can end up in a pickle. - -Generally the scripts are very careful to not wreck your files or your -patches. But they can get the ./applied-patches and ~-files into an -awkward state. - -Usually you can sort it out by copying the ~-files back onto the originals -and removing the last line from ./applied-patches. Or do a "refpatch ; -poppatch ; rm patches/troublesome-patch.patch ; cvs up patches". - -If it's really bad, just blow away the entire tree and do a new CVS checkout. - - -Working on non-kernel projects -============================== - -Well it's the same thing. Say you've downloaded a copy of util-linux -and you want to make a change: - - cd /usr/src - tar xvfz ~/util-linux.tar.gz - cd util-linux - mkdir pc patches txt - fpatch my-patch sys-utils/rdev.c - fpatch sys-utils/ipcs.8 - - refpatch - - -How to balls things up -====================== - -Well here's one way. Suppose you have 20 patches applied, and three of -them (say, "p1", "p6" and "p11") all modify "foo.c". - -Now you go and change foo.c. - -Well, to which patch does that change belong? You need to decide. -Let's say you decide "p6". - -If you run `refpatch' when "p11" is toppatch then you lose. The diff -went into p11. - -What you can do is: - -1: - poppatch p6 - - refpatch - pushpatch p11 - - - (See why ccache is looking good?) - -or - -2: - - - poppatch p6 - refpatch - - -Another good way of ballsing up is to cheat. Say "oh I just want to make -this one-line change". And "oh, and this one". - -Now you're getting in a mess. It's much, much better to just use the system: - - fpatch junk file1 - fpatch file2 - - - refpatch - poppatch - rm pc/junk.pc patches/junk.patch - -Merging with -mm kernels -======================== - -Haven't tried this, but it should work: - -- Grab all the patches from broken-out/, place them in your $P/patches/ - -- Copy my series file into ./series (or $P/pc/akpm-series and symlink it) - -- pushpatch 99 - -And you're off and running. The nice thing about this is that you can -send me incremental diffs to diffs which I already have. - -Or whatever. I'm fairly handy with diffs nowadays. Rejects are -expected. I just prefer to have "one concept per diff". - diff --git a/lustre/kernel_patches/scripts/export_patch b/lustre/kernel_patches/scripts/export_patch deleted file mode 100755 index d378417..0000000 --- a/lustre/kernel_patches/scripts/export_patch +++ /dev/null @@ -1,55 +0,0 @@ -#!/bin/sh - -. patchfns >/dev/null || . /usr/lib/patch-scripts/patchfns >/dev/null || { \ - echo "Impossible to find my library 'patchfns'." - echo "Check your install, or go to the right directory" - exit 1 -} - -usage() -{ - echo "export_patch: export the patches listed in ./series" 1>&2 - echo "usage: export_patch destination-directory [prefix] " 1>&2 - exit 1 -} - -DIR="$1" -PREFIX="$2""_" - -if [ "$DIR" = "" ] -then - usage -fi - -if [ -e "$DIR" -a ! -d "$DIR" ] -then - echo "$DIR exists already, but is not a directory." 1>&2 - exit 1 -fi - -if [ ! -r ./series ] -then - echo "./series is not readable." 1>&2 - exit 1 -fi - -mkdir -p "$DIR" || exit 1 - -count=1 -for x in `cat ./series` -do - fname=`echo "$count" "$PREFIX" "$x" |\ - awk '{ if ( $2 != "_" ) - printf("p%05d_%s%s\n", $1, $2, $3); - else - printf("p%05d_%s\n", $1, $3); - }'` - if [ ! -r $P/patches/"$x" ] - then - echo "$P/patches/"$x" is not readable. skipping." 1>&2 - continue; - fi - cp -f $P/patches/"$x" "$DIR"/"$fname" || continue; - count=`expr $count + 1` -done - diff --git a/lustre/kernel_patches/scripts/extract_description b/lustre/kernel_patches/scripts/extract_description deleted file mode 100755 index 6fa0e68..0000000 --- a/lustre/kernel_patches/scripts/extract_description +++ /dev/null @@ -1,87 +0,0 @@ -#!/bin/sh - -insert_line() -{ - PATTERN="$1" - LINE="$2" - FILE="$3" - awk ' BEGIN { found=0; } - /'"$PATTERN"'/ { - print; - if (!found) - printf("%s\n", "'$LINE'"); - found=1; - next; - } - { print; } - ' < "$FILE" -} - -# extract the description from the top of a patch -# filter stdin -# collapse adjacent blank lines to a single blank line -# remove any lines that look like diffstat output -# stop output on encountering a line beginning with '---' (beginning of patch) - - TMPFILE=`mktemp /tmp/xdtmp.XXXXXX` || exit 1 - formail -kfcb -X 'From:' -X 'Subject:' |\ - awk ' - BEGIN { found_end=0; lastone="x"; } - /^ .* [|] +[0-9]+ [+-]+$/ { - #/* we found something like diffstat output... */ - if (found_end == 1) { - /* we are past end of diffstat, let it pass */ - print; - } - next; - } - /^ [1-9][0-9]* files changed/ { - #/* end of diffstat output, stop filtering diffstat */ - found_end=1; - next; - } - /^--- / { exit; } - { - #/* collapse adjacent blank lines to 1 blank line */ - if ( $0 == "" && lastone == "" ) - next; - else - print; - lastone=$0; - } - ' | awk '{ if ($0 == "" && FNR == 1) next; print; }' > "$TMPFILE" - - descs=`head -10 $TMPFILE | grep -c '^[ ]*DESC[ ]*$'` - if [ "$descs" = "0" ] - then - # DESC is not 1st non blank line in the file - echo "DESC" - descs=0 - fi - edescs=`grep -c '^EDESC$' "$TMPFILE"` - subjects=`grep -c '^[ ]*Subject[:]' "$TMPFILE"` - froms=`grep -c '^[ ]*From[:]' "$TMPFILE"` - if [ "$edescs" = "0" ] - then - if [ "$subjects" != "0" ] - then - insert_line '^Subject[:]' 'EDESC' "$TMPFILE" - else - if [ "$froms" != "0" ] - then - insert_line '^From[:]' 'EDESC' "$TMPFILE" - else - if [ "$descs" = "0" ] - then - # blank DESC line... - echo '(undescribed patch)' - echo EDESC - cat "$TMPFILE" - else - insert_line '^DESC$' "EDESC" "$TMPFILE" - fi - fi - fi - else - cat $TMPFILE - fi diff --git a/lustre/kernel_patches/scripts/forkpatch b/lustre/kernel_patches/scripts/forkpatch deleted file mode 100755 index cef297c..0000000 --- a/lustre/kernel_patches/scripts/forkpatch +++ /dev/null @@ -1,76 +0,0 @@ -#!/bin/sh - -# -# Fork the next patch in the series -# - -. patchfns >/dev/null || . /usr/lib/patch-scripts/patchfns >/dev/null || { \ - echo "Impossible to find my library 'patchfns'." - echo "Check your install, or go to the right directory" - exit 1 -} - -usage() -{ - echo "Usage: forkpatch " - exit 1 -} - -if [ $# -ne 1 ] -then - usage -fi - -NEW=$1 -BASE=`stripit $NEW` -SERIES=series - -if [ ! -e $SERIES ] -then - echo 'File "series" not found' - exit 1 -fi - -if [ -f $P/$BASE.patch ] ; then - echo "Patch $NEW already exists as a file" - exit 1 -fi - -if grep $BASE $SERIES >& /dev/null ; then - echo "Patch $NEW already exists in series" - exit 1 -fi - -TMPSERIES=$(mktemp /tmp/series-XXXXXXXX) -top=$(toppatch) -if [ x"$top" == x ] -then - todo=$(head -1 $SERIES) -else - last_in_series=$(stripit $(tail -1 $SERIES)) - if [ $last_in_series == $top ] - then - echo "Series fully applied.
