LU-4895 lfsck: not create object to repair dangling by default

If the OST-object which is referenced by some MDT-object does not
exist, the layout LFSCK should not create the lost OST-object by
default; otherwise related application(s) may miss to be aware of
the bad file.

The LFSCK will allow the administrator to specify how to handle
the dangling reference case via a new option "-c" when trigger
the LFSCK:

[-coff] or [--create_ostobj=off]:
Report the inconsistency via log, but keep the dangling reference
there without repairing. (by default)

-c[on] or --create_ostobj[=on]:
Create the lost OST-object.

Change syntax for dryrun:
[-noff] or [--dryrun=off]:
Disable dryrun mode. (by default)

-n[on] or --dryrun[=on]:
Enable dryrun mode.

LU-4388 io: pass fsync() range through RPC/IO stack

The Linux VFS and Lustre OST_SYNC RPC are both capable of specifying
fsync() on a sub-extent of the file {start, end} instead of the full
file.  This allows less than the full amount of data to be flushed,
reducing or possibly eliminating the work needed before the syscall
can return.

However, the handling of sub-extent of the file for fsync was lost
with the move to CLIO on the client and OSD API on the server.  They
were ignoring the passed {start, end} and using {0, OBD_OBJECT_EOF}
instead.

Return the ability to pass a sub-extent for fsync() from the client,
to the specific stripes/OSTs that need the sync operation, and pass
it down to the OSD.  The ZFS OSD doesn't handle this yet, but there
is room for improvement in a separate patch.

LU-4927 scrub: rebuild stale OST OI mapping

If the osd_oi_lookup() which is called by osd_scrub_check_update()
returns -ESTALE for an OST FID, then it means that the target FID
has invalid OI mapping, and should be rebuilt.

LU-4819 tests: Lustre Sanity test_101b hangs for large OSTCOUNTs

sanity.sh test_101b hangs during Lustre sanity test. This

greater than 100.

Due to OSTCOUNT of more than 100, the ITERATION parameter
results in '0', which causes the 'reads' utility to run
in infinite 'for' loop. Thus resulting in a hang on such

LU-3319 procfs: fix symlink handling

While working on symlink handling for seq files I noticed a
long outstanding bug. Code was developed to link osc obds
to target_obds of the lov layer. The target_obds directory
was never created for the symlinks. This patch enables this
long forgotten feature. Also addressed is the race condition
experinced with server side code ported to seq_files that
used symlinks. To avoid the race the handle obd_proc_private
was moved from struct obd_device to struct obd_type which
now allows earlier registeration that only happens once.
The second problem addressed is the module loading race.
Several modules share the same top proc directory entry which
can become a issue if a client exist on a server node since
the linux proc system allows multiple directories of the same
name. Original Lustre had a lprocfs_srch but that doesn't
work if you use the kernels internal cache for the proc
system so you need to keep track of who grabs the proc root
first and then use the first one registered for when the
next module loads.

LU-4879 lfsck: avoid check exp_connect_flags before connected

It is possible that the connection among some MDTs and OSTs are not
ready yet when the LFSCK wants to start the scanning globally. Under
such case, the LFSCK RPC should trigger related initial connection or
recovery connection, but not check the exp_connect_flags() directly.

On the other hand, it is not important to check whether the remote
server to support the OBD_CONNECT_LFSCK or not, because if the peer
does not support the LFSCK, the lfsck_start RPC will get failure.

LU-4838 osd: object iterator in zfs to sync before iteration

The issue with dmu_object_next() is that it doesn't expose
non-committed blocks in the metadnode. Therefore the iterator
doesn't find dnodes allocated in the current (non-committed)

solution, osd_zfs_otable_it_init() ensures the current txg

LU-4847 mdc: use cl_max_mds_md to pack getattr RPC

In some cases, cl_default_mds_easize might be zero, especially for
MDC connected to non-MDT0, then mdc might pack getattr RPC with
zero eadatasize.

If client is trying to access remote striped directory with
zero eadatasize, MDT will not return layout information of the
striped direcotry, which will be mis-regarded as non-striped

So we should use cl_max_mds_easize if cl_default_mds_easize is zero.

It's not atomic to check the last reference and state of cl_lock

freed, if the process is preempted between atomic_dec_and_test()

nobody else can have any chance to use it again.
