LU-11369 hsm: allow non-owner writers to set HSM state dirty

In mdt_add_dirty_flag(), bump up the capability so that
mdt_hsm_attr_set() will succeed even if the writer (or truncater) is
not the owner of the file.

LU-8066 llite: make llite/lov and lmv symlinks

old proc code had /proc/sys/fs/lustre/llite/.../lov and lmv
dirs that contained name of the dir in lustre/lov and lustre/lmv
to better be able to find correct obd device there, but
I imagine a better solution would be to just create a symlink with
the same name. The name is then pointless and the target dir would
have uuid file just as if it was the old-style dir.

LU-8324 hsm: prioritize one RESTORE once in a while

Currently, HSM requests are run in the order they are submitted to
the coordinator. This has the undesirable side effect that the more
interactive requests (RESTORE / REMOVE) can take quite a while to be
run when a huge batch of ARCHIVE requests are already queued.

This patch is not a clean fix to LU-8324, it is merely an attempt at
making things bearable while a proper solution is being developped.

LU-8950 tests: do not use make_custom_file_for_progress()

Do not use make_custom_file_for_progress() in sanity-hsm in tests:
12c, 26, 27b, 28, 31b, 31c, 33, 34, 35, 36, 54, 55, 56, 60, 62, 71,
104, 200, 202, 221, 223b, 225, 251, 252, 407

Before this patch make_custom_file_for_progress() was used to create
big files (5MB to 40 MB). There were several use cases for that:
- in combination with the --bandwidth option of lhsmtool_posix, it
   allows synchronizing HSM operations and other things;
- to log enough "progress events", HSM operations need to last long
   enough (the --bandwidth option comes in handy too).

It needed to be removed because:
- archiving and restoring big files at a 1MB/s rate takes too much
   time (admittedly, that was the point);
- there are other way to have HSM operations occur concurently. For
   example: suspending copytools to delay request processing.
- make_custom_file_for_progress() does not correctly reflect what
   the function does and should be used for. Wherever big file are
   still needed, the patch uses create_file() instead.

Removing the need to archive or restore big files at a limited rate
represents quite a speed-up on sanity-hsm.

Allow short_io to be disabled completely if it is set to zero.

It would be nice to also change the name of the /proc functions
in a similar manner but that also changes the /proc tunable name
(via LUSTRE_RW_ATTR() macro) and has compatibility implications
for sites that may have changed this value.

LU-8066 llite: change how "dump_page_cache" walks a hash table

The "dump_page_cache" seq_file currently tries to encode
a location in the hash table into a 64bit file index so that
the seq_file can seek to any location.

This is not necessary with the current implementation of seq_file.
seq_file performs any seeks needed itself by rewinding and calling
->next and ->show until the required index is reached.

The required behaviour of ->next is that it always returns the next
object after the last one returned by either ->start or ->next.
It can ignore the ppos, but should increment it.

The required behaviour of ->start is one of:
1/ if *ppos is 0, then return the first object
2/ if *ppos is the same value that was passed to the most recent call
to either ->start or ->next, then return the same object again
3/ if *ppos is anything else, return the next object after the most
recently returned one.

To implement this we store a vvp_pgcache_id (index into hash table)
in the seq_private data structure, and also store 'prev_pos' as the
last value passed to either ->start or ->next.

We remove all converstion of an id to a pos, and any limits on the
size of the vpi_depth.

vvp_pgcache_obj_get() is changed to ignore dying objects so that
vvp_pgcache_obj only returns NULL when it reaches the end of a hash
chain, and so vpi_bucket needs to be incremented.

A reference to the current ->clob pointer is now kept as long as we
are iterating over the pages in a given object, so we don't have to
try to find it again (and possibly fail) for each page.

And the ->start and ->next functions are changed as described above.

LU-11187 ldiskfs: don't mark mmp buffer head dirty

Marking mmp bh dirty before writing it will make writeback
pick up mmp block later and submit a write, we don't want the
duplicate write as kmmpd thread should have full control of
reading and writing the mmp block.
Another reason is we will also have random I/O error on
the writeback request when blk integrity is enabled, because
kmmpd could modify the content of the mmp block(e.g. setting
new seq and time) while the mmp block is under I/O requested
by writeback.

LU-10030 clio: don't use spare bits in iattr.ia_valid

Using spare bits in iattr.ia_valid is not safe as the
bits might get used for some other purpose without
us noticing.

Lustre currently used 4 spare bit, but they are all
defined in different places so this isn't immediately
obvious.

This patch brings all those bit definitions together
and defined a new op_data field (op_xvalid) to hold
the extra validity bits.

It also replaces sa_valid in struct cl_setattr_io
with sa_avalid and sa_xvalid. Changing the name is
helpful as sa_valid already has another use within
lustre.

LU-8174 misc: name open file handles as such

In a number of places in the code, rename variables from "*_handle"
or "*_fh" to "*_open_handle" so that it is clear this is referencing
an open file handle rather than something else (e.g. a lock handle).

Also rename the confusingly-named mti_close_handle to mti_open_handle,
since this is referencing an open file handle, even if it is used at
close time to close the file.

   mfd_handle2mfd() -> mfd_open_handle2mfd()
   mdt_file_data.mfd_handle -> mfd_open_handle
   mdt_file_data.mfd_old_handle -> mfd_open_handle_old
   mdt_thread_info.mti_close_handle -> mti_open_handle
   mdt_body.mbo_handle -> mbo_open_handle
   mdt_io_epoch.mio_handle -> mio_open_handle
   md_op_data.op_handle -> op_open_handle
   mdt_rec_create.cr_old_handle -> cr_open_handle_old
   mdt_reint_record.rr_handle -> rr_open_handle
   obd_client_handle.och_fh -> och_open_handle

Change the resync code path to use a "lease_handle" to avoid confusion
with an open handle:

   mdt_rec_resync.rs_handle -> rs_lease_handle
   use md_op_data.op_lease_handle
   add mdt_reint_record.rr_lease_handle

LU-11392 llog: fix race llog_process_thread vs llog_add

The llog should be wrapped so it has old data on disk and zero at
bitmap.
  1. llog_process_thread reads part of llog at buffer.
  1. process a last record, checks the next record fields
  2. llog_add adds a record and marks new record at bitmap
  1. check bitmap flag and process the old record from buffer

After LU-7001 small window for the race still exists. It locates
between partial_chunk check and ext2_test_bit.
The patch fixes this race.

LU-10177 lfs: support DOM-to-OST migration

Migraton of DoM file to an OST file is possible with
'lfs migrate' command in general but would cause space loss
on MDS, because DOM local inode blocks are not deleted.
Patch doesn the following:
- adds truncate for local MDS inode after migration.
- check and prevent migration from non-DOM to DOM file,
that will be done later with mirroring.
- prohibit 'lfs swap_layouts' command if either file has
DOM component, 'lfs migrate' should be used instead

LU-11373 libcfs: fix wrong check in libcfs_debug_vmsg2()

Logic here is we skip output if time is before @cdls_next
reach and increase @cdls_count. however we did it in the
opposite way:

1)libcfs_debug_vmsg2() is called for a long time, that means
current check succeed, we skip print messages and return, we
will skip all messages later too..

2)libcfs_debug_vmsg2() is called frequently, current check
fail every time, message will be bumped out always. the
worst case is we never skip any messages.

Also fix test case to cover this later which is from Andreas:

The test_60a() llog test is being run on the MGS, while the
check in test_60b() to confirm that CDEBUG_LIMIT() works properly
is being run on the client. There has been a breakage in
CDEBUG_LIMIT() that this test failed to catch, now we need to
track it down.

Change test_60b to dump the dmesg logs on the MGS.

LU-8066 llite: remove redundant lookup in dump_pgcache

Both the 'next' and the 'show' functions for the dump_page_cache
seqfile perform a lookup based on the current file index. This is
needless duplication.

The reason appears to be that the state that needs to be communicated
from "next" to "show" is two pointers, but seq_file only provides for
a single pointer to be returned from next and passed to show.

So make use of the new 'seq_private' structure to store the extra
pointer.
So when 'next' (or 'start') find something, it returns the page and
stores the clob in the private area.
'show' accepts the page as an argument, and finds the clob where it
was stored.

LU-4684 lmv: support accessing migrating directory

Migrating directory contains stripes of both old and new layout, and
its sub files may be located on either one. To avoid race between
access and new creations, there are 4 rules to access migrating
directory:
1. always create new file under new layout.
2. any operation that tries to create new file under old layout will
   be rejected, e.g., 'mv a <migrating_dir>/b', if b exists and is
   under old layout, this rename should fail with -EBUSY.
3. operations that access file by name should try old layout first,
   if file doesn't exist, then it will retry new layout, such
   operations include: lookup, getattr_name, unlink, open-by-name,
   link, rename.
4. according to rule 1, open(O_CREAT | O_EXCL) and create() will
   create new file under new layout, but they should check existing
   file in one transaction, however this can't be done for old
   layout, so check existing file under old layout on client side,
   then issue the open/create request to new layout.

Disable sanity 230d for ZFS backend because it will trigger lots of
sync, which may cause system hung.

LU-11303 out: clean up osp_update_rpc_pack() macro

The osp_update_rpc_pack() macro was using both an operation "name"
argument as well as an "opcode" argument, but totally ignoring the
"opcode" argument.  This allowed a caller in osp_attr_set() to pass
a non-existent opcode name to the function that was ignored.

The function also concatenated the passed name string to generate
a function name to be called (which supplied its own opcode value).
This name concatenation obscures the code functionality, since the
called functions are not actually referenced directly in the code.

Instead, pass the function name as the argument, and drop the opcode
completely.  This at least makes it possible to see where the function
is being called.  Change the macro to be upper-case, so that it is
more clear that it is a macro rather than a real function.  It would
be better to replace the macro with an actual function, but this is
not very practical due to the use of variable-length argument lists.

The dump_page_cache debugfs file allocates and frees an 'env' in each
call to vvp_pgcache_start,next,show. This is likely to be fast, but
does introduce the need to check for errors.

It is reasonable to allocate a single 'env' when the file is opened,
and use that throughout.

So create 'seq_private' structure which stores the sbi, env, and
refcheck, and attach this to the seqfile.

Then use it throughout instead of allocating 'env' repeatedly.

LU-4684 migrate: shrink dir layout after migration

Use setxattr(XATTR_NAME_LMV) to shrink dir layout after migration,
this may change dir fid because it may shrink dir to 1-stripe, if so
replace this dir with its stripe.

LU-4684 migrate: migrate striped directory

Migrate striped directory in below steps:
1. create target object if needed: if source is directory, a
   target object is always created, otherwise if source is
   already located on the target MDT, or source still has
   link on source MDT, then skip creating.
a) if source is directory, detach source stripes and
   attach them to target.
b) migrate source xattrs to target.
c) if source is regular file, update PFID to target
   fid.
d) update fid to target for all links of source
2. update namespace
a) migrate dirent from source parent to target parent.
b) update linkea parent fid to target parent.
c) destroy source object.

This implementation improves following fields:
1. all involved objects are locked to avoid race.
2. directory migration doesn't migrate its dir entries, instead
   it's done in each sub file migration, this avoids timeout in
   migrating dir entries for large directory, and also avoids
   touching dir entries without lock.
3. file/dir is migrated in one transaction, so migrate recovery
   is the same as others.
4. migrating directory can be accessed (modifiable) like normal
   directory.
5. if migration of sub files under a directory fails, user can
   redo migrate to finish migration of this directory.

Disable migrate in racer.sh.

is for this purpose. However, truncate will change
file data but it doesn't revoke lease lock.

This patch fixes the issue by acquiring open sem,
checking lease count and revoking lease if there exists
any pending lease on the file.
