LU-8116 build: Fix libmount configure message

The configure messages for libmount checking were incorrectly nested resulting
in messages like this:

checking whether build with libmount... checking libmount/libmount.h usability... no
checking libmount/libmount.h presence... no
checking for libmount/libmount.h... no
no

This patch unwinds that mistake.

When we hit Lustre crash, e2fsck always complains of Quota

LU-8220 tests: stripe file over all active OSTs

In test_iozone/parallel-scale-cifs, the iozone command creates the
temporary files under test with default stripe count=1, that is,
both the 256mb files reside on the same OST, over-utilizing the OST,
resulting in Use%=100%(No space left on device).

The fix is to create a sub-directory in the samba server mount
point with a stripe count of -1 (stripe over all available OSTs)
and then run iozone with this sub-directory path, so that all the
temporary files created within this sub-directory, during iozone,
reside on multiple OSTs and OST free space is utilized uniformly.

Since the test suite mounts lustre client on smb server, the "lfs
setstripe" command is executed on the smb server.

However, there are still unresolved issues that need to be
addressed and a longer transition period needed before the
old functionality can be removed.

Remove the deprecation warning for now, rather than bumping it

LU-7434 ptlrpc: lost bulk leads to a hang

This is a combination of two commits. The original commit from:
http://review.whamcloud.com/17221
and a fix to that commit from:
http://review.whamcloud.com/19758

Description of the original patch:
The reverse order of request_out_callback() and reply_in_callback()
puts the RPC into UNREGISTERING state, which is waiting for RPC &
bulk md unlink, whereas only RPC md unlink has been called so far.
If bulk is lost, even expired_set does not check for UNREGISTERING
state.

The same for write if server returns an error.

This phase is ambiguous, split to UNREG_RPC and UNREG_BULK.

The fix to the original commit was originally pushed against LU-8062.
That fix is described thusly:
LU-8062 test: fix fail_val in recovery-small/115b

The fail_loc OBD_FAIL_OST_ENOSPC is caught in 2 places:
1. ofd_statfs() - where it is checked against the fail_val
and if fail_val matches the OST ID it is caught here
itself and hence test fails.
2. tgt_brw_write() - the actual place where the fail_loc should
be caught.

The patch makes the fail_loc to be caught at the appropriate place
by setting the fail_val to $OSTCOUNT. So even if fail_loc is set
in the statfs part it is not caught there and therefore caught in
tgt_brw_write().

LU-7934 osp: fix tr->otr_next_id overflow

The tracker next_id and current_id u32 type was based on
max llog records. But llog use cyclic store for records, so
llog could store infinite number of records and limited by
max number at moument of time. The u32 type could be
overflowed easy if a server isn`t rebooted.
osp_sync_id_get()) snx11126-OST0045-osc-MDT0000: next 0,
last synced 4294967205
This fix changes type u32 to u64 for *id. Now, we store only
low part current_id to llog record header id. And restore the
full u64 from record header later. It is possible because
llog catalog can store 64768^2 and it is less than u32 max value.

LU-8171 hsm: stack overrun in hai_dump_data_field

With the stock 3.10 kernel, hai_dump_data_field will do a stack buffer
overrun when cat'ing /proc/fs/lustre/.../hsm/actions if an action has
some data in it.

hai_dump_data_field uses snprintf. But there is no check for
truncation, and the value returned by snprintf is used as-is.  The
coordinator code calls hai_dump_data_field with 12 bytes in the
buffer. The 6th byte of data is printed incompletely to make room for
the terminating NUL. However snprintf still returns 2, so when
hai_dump_data_field writes the final NUL, it does it outside the
reserved buffer, in the 13th byte of the buffer. This stack buffer
overrun hangs my VM.

This doesn't happen on CentOS 6.

Fix by checking that there is enough room for the next 2 characters
plus the NUL terminator. Don't print half bytes. Change the format to
02X instead of .2X, which makes more sense.

LU-7302 scrub: join the running OI scrub properly

Sometimes, the OI scrub can be triggered as partial mode by
randomly found inconsistent OI mapping(s). Under such case,
if the sysadmin triggers LFSCK/OI scrub (full mode) manually,
the partial mode OI scrub needs to be converted as full mode
via osd_scrub_join(). Before that, it will check whether the
current OI scrub is full mode or not. Originally, we checked
the SF_AUTO flags (scrub::os_file.sf_flags) only, but ignored
the partial mode (scrub::os_partial_scan). The partial mode
OI scrub will NOT change the scrub iteration cursor (srub::
os_pos_current). So if miss to convert the partial OI scrub,
the subsequent inode table based iteration will be blocked
inside osd_otable_it_next() as following:

if (it->ooi_cache.ooc_pos_preload >= scrub->os_pos_current)
        l_wait_event(thread->t_ctl_waitq,
                     osd_otable_it_wakeup(scrub, it),
                     &lwi);

This patch fix such issue by checking the conditions properly.

LU-7997 obd: RCU stalls in lu_cache_shrink_count()

The algorithm for counting freeable objects in the lu_cache shrinker
does not scale with the number of cpus. The LU_SS_LRU_LEN counter
for each cpu is read and summed at shrink time while holding the
lu_sites_guard mutex. With a large number of cpus and low memory
conditions, processes bottleneck on the mutex.

This mod reduces the time spent counting by using the kernel's percpu
counter functions to maintain the length of a site's lru. The summing
occurs when a percpu value is incremented or decremented and a
threshhold is exceeded. lu_cache_shrink_count() simply returns the
last such computed sum.

This mod also replaces the lu_sites_guard mutex with a rw semaphore.
The lock protects the lu_site list, which is modified when a file
system is mounted/umounted or when the lu_site is purged.
lu_cache_shrink_count simply reads data so it does not need to wait
for other readers. lu_cache_shrink_scan, which actually frees the
unused objects, is still serialized.

LU-6861 scrub: only trigger full OI scrub when necessary

Generally, scanning the whole device for OI scrub routine check may
takes some long time. If the whole system only contains several bad
OI mappings, then it is not worth to trigger OI scrub automatically
with full speed when some bad OI mapping is auto-detected. Instead,
we can make the OI scrub to fix the found bad OI mappings only, and
if more and more bad OI mappings are found as to exceeds some given
threshold that can be adjusted via some proc interface, then the OI
scrub will run with full speed to scan whole device.

Our current OI scrub auto-trigger control mechanism can avoid most
of unnecessary whole-device based scanning. But it missed one case
that the FID lookup for remote MDT-object and may cause unexpected
whole-device based OI scrub. This patch is for handle such corner.

Fix the sanity-scrub.sh test_4a, test_4b, and test_4c to search for
"prior_updated" and not "updated_prior" in the scrub status file.
