LU-1299 clio: a combo patch to fix cl_lock

In this patch, the following issues are fixed:
* redefine cl_lock_error(). There are two kinds of error when
  enqueuing a cl_lock: internal errors return from server side and
  local error for example interrupted by signal when waiting for a
  lock. Obviously the latter one is not fatal so we shouldn't err the
  lock out;
* for fault handling, only signal SIGKILL and SIGTERM is not allowed;
* handle return code of ll_fault correctly;
* redefine ->unuse() to release resource it held if enqueuing lock
  failed;
* in cl_lock_hold_release(), only CLS_CACHED mode lock will be cached,
  for locks in other states, they will be cancelled voluntarily;
* fix the problem that cfs_block_sigs() is wrongly used as
  cfs_restore_sigs() and implementation of cfs_block_sigs() was wrong
* Unuse method releases the underneath resources even error occurs, so
  we should set the lock to be CLS_NEW anyway.
* other minor fixes.

LU-1623 mdt: Atomically update MDT export connection flags

MDT processing of connect requests currently updates the export
connection flags in two steps: client/server feature matching is
performed first, then much later various security-related bits are
removed as needed.  Certain error paths may leave the export flags
partially initialized.

A problem arises if multiple connect requests from the same client are
handled out of order, as may occur due to network disruptions. If the
last such request to be handled has a lower connection count than one
that already completed, it will be aborted with -EALREADY after having
modified the connection flags in the export.  However, the
security-related flags are left with incorrect values, as the
top-level connect handler skips setting these in the error path.
Replies to subsequent client requests may then contain unexpected
security information, causing the client to crash.

Similar issues may exist with other target types having non-atomic
export flag updates, and these should be addressed in follow-up
patches.

This patch makes the following changes:

- To avoid the problem described above, update the export connection
  flags atomically, and only in the successful case.

- To make this important atomic operation more conspicuous, move it
  from mdt_init_sec_level() to the top-level handler mdt_connect().

- Add a comment to mdt_connect_internal(), and delete a disabled code
  block from it.

- Correct debug message in target_handle_connect() to match code.

(commit bd8835cc2dde6e86701650ccf90423ecd8fb042e) since the threads
are a property of the MDS, not of the MDT(s) on the system.

is possible to upgrade 1.8->2.1->2.4 without problems.  No message
is printed in 2.1.x about deprecation, since it isn't possible to use
only one or the other in 2.1, and a warning will be printed in 2.3+

LU-1689 tests: fix mount during e2fsck test

The current mmp test 8 (mount during e2fsck) has two time issues:
1) the mount operation may start before e2fsck
2) the e2fsck operation may stop before mount

This patch fixes the above issues by providing enough time for e2fsck
operation to be started before mount operation, and setting the
superblock free_blocks_count field with 0 to force e2fsck checking
the Lustre server target device, which provides enough time for

LU-1493 quota: extra release caused by race

There is a race between the check_cur_qunit() and the
dqacq_completion(): check_cur_qunit() read hardlimit
and calculate how much quota need be acquired/released
based on the hardlimit, however, the hardlimit can be
changed by the dqacq_completion() at anytime. So that
could result in extra quota acquire/release when there
is inflight dqacq.

In general, such extra dqacq dosen't bring fatal error,
unless an extra release is going to release more than
'hardlimit' quota.

To minimize the code changes (anyway, it'll be totally
rewritten in the new quota design), we just do one more
check here to avoid the extra release which could bring
fatal error. A better solution could be calculating the
qd_count here and removing the lqs_blk/ino_rec stuff.

LU-1129 obdfilter: handle race condition of recreating objects

During OST recovery, a race can happen while handling replayed
OST_WRITE request during the MDS->OST orphan recovery period to
recreate missing objects, which can trigger ASSERTION(diff >= 0)
failure.

This patch handles the above issue by adding obd->obd_recovering
into the assertion to check whether the OST is in recovery or not.
If it's in recovery and diff < 0, then no assertion failure occurs,
the object has been recreated. If the OST is not in recovery and
diff < 0, then the assertion failure occurs.

LU-1428 ldlm: fix a race in ldlm_lock_destroy_internal

ldlm_lock::l_exp_hash should be protected by internal lock of

export::exp_lock_hash is in progress of rehashing (thread context of
cfs_workitem), there could be tiny window between deleting this lock
from bucket[A] and re-adding it to bucket[B] of l_exp_hash, and
cfs_hlist_unhashed(lock::l_exp_hash) will return 1 in this window,
then we destroyed a lock but left it on l_exp_hash forever because
lock::l_destroyed has been set to 1 and ldlm_lock_destroy_internal()
wouldn't be able to remove the lock from l_exp_hash even it's called

This patch gives the ability to control the number of kib scheduler
threads launched by the ko2iblnd module, via a kernel module option.

Indeed, we can have some situations where the default threads number
is not appropriate. The default value is to create as many threads as
the number of CPU cores.

On certain platforms, we have noticed a performance penalty
when running too many kib scheduler threads.
