LU-7055 osd: move dput() out of osd_ost_fini()'s rwlock

osd_ost_fini() calls into osd_seq_free() under write lock, which
in turn calls into dput() that might sleep and cause "BUG: rwlock
wrong CPU on CPU#x, umount/xxx" sort of messages.
To fix this issue, this patch only keeps list_del_init() under
write lock, and moves sleeping function out of there.

    Don't take spinlock in tgt_cb_last_committed, if
    exp_last_committed was updated with higher trasno.
    Also change list_add_tail to list_add. It gives
    advantages to ldiskfs in tgt_cb_last_committed.
    In the beginning of list will be placed thandles
    with the highest transaction numbers. So at the
    first iterations we will have the highest transno.
    It will save from extra call of
    ptlrpc_commit_replies.

LU-7828 statahead: set sai_index_wait with lli_sa_lock held

It is the sponsor thread of the statahead thread to update the
sai::sai_index_wait. Originally, it didn't hold the lli_sa_lock
when did that. Becuase of out-of-order execution others may miss
to wakeup such thread.

On the other hand, if the statahead RPC gets failure, it should
wakeup the sponsor thread, not the statahead thread.

LU-7699 build: Replace version_tag.pl with LUSTRE-VERSION-GEN

This patch overhauls how version numbers are handled.

The biggest change is removing the two independent
places where versions were being generated (LB_BUILDID and
lustre_tag*.pl) with a single script named LUSTRE-VERSION-GEN
at the top level of the tree.  LUSTRE-VERSION-GEN is based
on the GIT-VERSION-GEN script that git's own source code build
system uses.

LUSTRE-VERSION-GEN generates the lustre version string from
either git, or if git is not available from the LUSTRE-VERSION-FILE
file, or if _that_ is not available, its own internal DEFAULT_VERSION
default version number.  This allows building the lustre code under
all reasonable conditions.

The new method uses LUSTRE-VERSION-GEN to supply the correct
full lustre version (which may contain git --describe information)
to AC_INIT.  This means that the autotools actually know the
correct version number.  Some benefits of this are:

* We can use standard {AC_}PACKAGE_VERSION macros and variables
  instead of inventing our own
* ./configure --version and other commands will list the correct
  version of Lustre
* The lustre tarball created by "make dist" will contain the full
  version number

The lustre/autoconf/lustre-version.ac file was replaced with
a new config/lustre-version.m4 file.  We no longer need to work
with m4-only macros prefore AC_INIT is called, so the new
file defines a LUSTRE_VERSION_VARIABLES function for us to call
from configure.ac.  The new lustre-version.m4 derives the
derive LUSTRE_{MAJOR,MINOR,PATCH,FIX} from AC_PACKAGE_VERSION
rather than being yet another source of version numbers.

The LUSTRE_VER_ALLOWED_OFFSET and LUSTRE_CLI_VER_OFFSET_WARN
m4 macros were dropped, and the OBD_OCD_VERSION strings stored
directly in lustre_ver.h.in instead.

LB_CHECK_VERSION was removed (no longer necessary).

AC_LUSTRE_VERSION_STRING was drop.  It is no longer necessary
now that we can set LUSTRE_VERSION_STRING directly to
@PACKAGE_VERSION@ in lustre_ver.h.in.

The DOWNSTREAM_RELEASE configure argument is deprecated and all
related code removed.

The lustre/doc/VERSIONING documenation is relocated to
Documentation/versioning.txt and updated to reflect the new versioning
method and practices.

The META file and BUILDID variables and related code are removed
since they are no longer used under the new versioning method.

Note that this patch makes lustre only look at the dotted version
tags in git, so we can finally stop using three to five tags for
every release.  Now we can just use one clear tag.  The tags
with underscores are obsolete.

weird non-standard way. Intel added support into Lustre to rpm package it.
While those additions use words like "cross_build", making it sound like it
might be generic, it really isn't.

All of that is really messy and non-standard, and it is making far too
difficult to package Lustre for normal rpm-based distributions.

Hopefully this won't be too much of a problem for Intel, because Phi
processors are now self-hosting.

This is in large part a revert of commit
  426194de03ad47497e99d281d86b5cdfc5142148:
"LU-2784 build: Provide RPMs build for Xeon Phi(TM) card"

LU-7524 fld: fld_clientlookup retries next target

fld_client_lookup() retries for another target, if the remote
target is deactive. This was introduced in
http://review.whamcloud.com/#/c/14313/ For getting the
next export target from the list, we use:
target = list_entry(target->ft_chain.next, struct
lu_fld_target,ft_chain);

Now for tests that deactivate the last target,
&(target->ft_chain) is the last entry in the list, and the
next of the last entry(target->ft_chain.next) is the list_head.
Using the macro list_entry maps the list_head pointer back into
a pointer to the structure that contains the list_head. Thus,
it turns the head of the list into its containing
structure(lu_fld_target).
Hence, since the head of the list does not have any data
associated with it, the containing structure(i.e.target)
formed from the head of the list also does not have any data.
Therefore, an export target with no obd device data is generated.
This corrupted export target(generated from the head of the
list) causes the assertion.

The fix is: While fld_client_lookup retries for another target,
if the next entry in the export target list is the head of the
list(&fld->lcf_targets), move to the next entry after the
head(target->ft_chain.next->next) and retrieve the target.
Else retrieve the next target entry(target->ft_chain.next).

LU-7256 tests: wait current LFSCK to exit before next test

During the sanity-lfsck tests, some test cases only check the
LFSCK status on MDT0, and go ahead if the status matches the
expected one. For DNE cases, such check maybe not enough, and
may leave un-finished LFSCK instances on other MDT(s). It may
cause the following trouble:

1) When move to next test case, the un-finished LFSCK instance
   may cause new LFSCK instance failure or other strange LFSCK
   check/repair behaviour.

2) If it is the last test case, and some MDT(s) umounted, then
   when some un-finished LFSCK instance on another online MDT
   needs to talk with some umounted MDT, then related RPC will
   trigger reconnect to the umounted MDT, and the LFSCK engine
   will hung there till such MDT mount again. That is the case
   for this ticket hit. In fact, we should allow the server to
   umount even though some LFSCK instances run on other nodes.
   The LU-6684 patch (http://review.whamcloud.com/#/c/17032/)
   will handle that more properly.

This patch is mainly for adjusting test scripts to wait all
the LFSCK instances to exit before the next test case.

There are two options to wait all the LFSCK instances to exit:

1) Check the LFSCK status via related lproc interface on each
   target (MDT/OST) one by one.

2) Export some new interface to check all the LFSCK instances'
   status via single command.

We choose the later solution. Because it is convenient for the
sys-admin. The new interface is 'lctl lfsck_query'. Its usage:

lctl lfsck_query <-M | --device MDT_device> [-h | --help]
                 [-t | --type check_type[,check_type...]]
                 [-w | --wait]

options:
-M: device to query LFSCK on.
-t: LFSCK type(s) to be queried (default is all).
-w: do not return until LFSCK not running.
-h: help message.

LU-2049 grant: add support for OBD_CONNECT_GRANT_PARAM

Add support for grant overhead calculation on the client side.
To do so, clients track usage on a per-extent basis. An extent is
composed of contiguous blocks.
The OST now returns to the OSC layer several parameters to consume
grant more accurately:
- the backend filesystem block size which is the minimal grant
  allocation unit;
- the maximum extent size;
- the extent insertion cost.
Clients now pack in bulk write how much grant space was consumed for
the RPC. Dirty data accounting also adopts the same scheme.

Moreover, each backend OSD now reports its own set of parameters:
- For ldiskfs, we usually have a 4KB block size with a maximum extent
  size of 32MB (theoretical limit of 128MB) and an extent insertion
  cost of 6 x 4KB = 24KB
- For ZFS, we report a block size of 128KB, an extent size of 128
  blocks (i.e. 16MB with 128KB block size) and a block insertion cost
  of 112KB.

Besides, there is now no more generic metadata overhead reservation
done inside each OSD. Instead grant space is inflated for clients
that do not support the new grant parameters. That said, a tiny
percentage (typically 0.76%) of the free space is still reserved
inside each OSD to avoid fragmentation which might hurt performance
and impact our grant calculation (e.g. extents are broken due to
fragmentation).

This patch also fixes several other issues:

- Bulk write resent by ptlrpc after reconnection could trigger
spurious error messages related to broken dirty accounting.
The issue was that oa_dirty is discarded for resent requests
(grant flag cleared in ost_brw_write()), so we can legitimately
have grant > fed_dirty in ofd_grant_check().
This was fixed by reseting fed_dirty on reconnection and skipping
the dirty accounting check in ofd_grant_check() in the case of
ptlrpc resend.

- In obd_connect_data_seqprint(), the connection flags cannot fit
  in a 32-bit integer.

- When merging two OSC extents, an extent tax should be released
  in both the merged extent and in the grant accounting.

LU-7437 utils: continue on errors in lctl {get,set}_param

The lctl get_param, list_param, and set_param code was accidentally
changed from "handle all parameters and return any error at the end"
to "stop at the first failed parameter and return an error".

The "try all parameters" behaviour was originally implemented by

but appears to have recently been broken in v2_7_63_0-45-g2d11035
by http://review.whamcloud.com/17223 moving lprocfs_param_pattern()
into the parameter handling loop rather than in the *param_display()
functions.  The new error handling for lprocfs_param_pattern() was
handled as an error, when it would previously only have been saved.
This was further aggrivated by the reorganization to cfs_get_paths()
in v2_7_66_0-10-g85cbe1a.

Restore the old error handling and add tests to verify it works.

messages printed by param_display(), since this is available.

The cfs_get_paths() patch also broke "lctl list_param -D" handling
(print only directories) by returning an error when this option was
used because display_param() returned NULL for non-directories (so
they wouldn't be printed), but the error handling treated this as
ENOMEM.  Move the handling for non-directories out of display_param
to avoid this, and add a test for "lctl list_param -D".

Fix a new memory leak in display_name() if realloc() fails.  Use the
existing param_name and don't append the type suffix in this case.

LU-7579 osd: move ORPHAN/DEAD flag to OSD

If a directory is unlinked while it is opened, then
it will set LUSTRE_ORPHAN_FL flag to osd object, so
the remote target can get this status by dt_attr_get().

And also LUSTRE_ORPHAN_FL will be stored inside
LMA (converted to LMAI_ORPHAN). In the meantime,
it will remove LUSTRE_SLAVE_DEAD_FL flag for dead
stripes of a striped directory, i.e. all of
dead directories (stripes) will use LMAI_ORPHAN
in LMA to indicate the status.

Also in osp_xattr, it should retrieve the return
value from the reply, which is the real length of
EA, instead of using reply buffer length.
