LU-7354 osd: avoid NULL pointer in osd_obj_update_entry

In osd_obj_update_entry(), the variable @oi_fid may be NULL.
We need to check such case before further using it to avoid

LU-7230 llite: clear dir stripe md in ll_iget

If ll_iget fails during inode initialization, especially
during striped directory lookup after creation failed,
then it should clear stripe MD before make_bad_inode(),
because make_bad_inode() will reset the i_mode, which
can cause ll_clear_inode() skip freeing those stripe MD.

Remove the name entry from the directory, once creation
failed. Note: this will not rollback all of local
operation, and LFSCK will take care of the orphan object.

Add sanity.sh 300p to verify the case.

And also enable lfs rm_entry for local object as well,
because sometimes it is quite possible to create the
local corrupted striped directory, and we might need
use "lfs rm_entry" to delete the corrupted striped dir.

LU-1032 build: DKMS RPM for Lustre Client modules

Permit Lustre Client (only) modules DKMS RPM creation.

This patch is a follow on to the first set of patches for LU-1032
that only allowed for the creation of Lustre Server (zfs only)
modules DKMS RPM.

It also changes original behavior by allowing to dynamically
modify dkms.conf on-target. This particularly helps to change
configure and list of modules to be built/installed list, like
to configure with gss to build ptlrpc_gss.ko module when
krb5_devel is present instead to have it been a mandatory
required dependency.

Also implements feature of DKMS RPM creation from Makefile
(thanks to mjmac), now in 2 separate SRPM/RPM steps and for both
Client and Server versions.

Also use an auto-increment (Array[${#Array[@]}]=) operator in
dkms.conf modules declarations to help for future changes when
there will be a need to add/delete modules.

Change in lustre/utils Makefile has been required to allow
building of ptlrpc_gss module with --enable-gss and without the
need to specify --enable-utils which was causing an unexpected
zfs user-land dependency for DKMS Server build.

To satisfy lustre rpm requirement of a package providing
lustre-osd, provides has been added to DKMS Server RPM since
it does actually generate osd-zfs module.

LU-7091 mdd: refresh nlink after update linkea

It should refresh nlink after update linkea, because
it might decrease the nlink of source object,
otherwise it might try to delete the stripeEA with
wrong nlink.

And also before migration, it should check if all
of the parents of the migrating object are in the
target MDT, only checking if these parents parent
are remote is not enough.

LU-7195 jobstats: Allow setting static content for jobid_var

* Support for accessing the .zfs/snapshot over NFS.
* Support for estimating send stream size when source is a bookmark.

* New zdb -ddddd can print details of block pointer objects.
* New zdb -b performance improved.
* New zstreamdump -d prints contents of blocks.

New Feature Flags

* large_blocks - This feature allows the record size on a dataset to
be set larger than 128KB. We currently support block sizes from 512
bytes to 16MB. The benefits of larger blocks, and thus larger IO, need
to be weighed against the cost of COWing a giant block to modify one
byte. Additionally, very large blocks can have an impact on I/O
latency, and also potentially on the memory allocator. Therefore, we
do not allow the record size to be set larger than zfs_max_recordsize
(default 1MB). Larger blocks can be created by changing this tuning,
pools with larger blocks can always be imported and used, regardless
of this setting.

* filesystem_limits - This feature enables filesystem and snapshot
limits. These limits can be used to control how many filesystems
and/or snapshots can be created at the point in the tree on which the
limits are set.

*Performance*

* Improved zvol performance on all kernels (>50% higher throughput,
  >20% lower latency)
* Improved zil performance on Linux 2.6.39 and earlier kernels (10x
  lower latency)
* Improved allocation behavior on mostly full SSD/file pools (5% to
  10% improvement on 90% full pools)
* Improved performance when removing large files.
* Caching improvements (ARC):
** Better cached read performance due to reduced lock contention.
** Smarter heuristics for managing the total size of the cache and the
   distribution of data/metadata.
** Faster release of cached buffers due to unexpected memory pressure.

*Changes in Behavior*

* Default reserved space was increased from 1.6% to 3.3% of total pool
capacity. This default percentage can be controlled through the new
spa_slop_shift module option, setting it to 6 will restore the
previous percentage.

* Loading of the ZFS module stack is now handled by systemd or the
sysv init scripts. Invoking the zfs/zpool commands will not cause the
modules to be automatically loaded. The previous behavior can be
restored by setting the ZFS_MODULE_LOADING=yes environment variable
but this functionality will be removed in a future release.

* Unified SYSV and Gentoo OpenRC initialization scripts. The previous
functionality has been split in to zfs-import, zfs-mount, zfs-share,
and zfs-zed scripts. This allows for independent control of the
services and is consistent with the unit files provided for a systemd
based system. Complete details of the functionality provided by the
updated scripts can be found here.

* Task queues are now dynamic and worker threads will be created and
destroyed as needed. This allows the system to automatically tune
itself to ensure the optimal number of threads are used for the active
workload which can result in a performance improvement.

* Task queue thread priorities were correctly aligned with the default
Linux file system thread priorities. This allows ZFS to compete fairly
with other active Linux file systems when the system is under heavy
load.

* When compression=on the default compression algorithm will be lz4 as
long as the feature is enabled. Otherwise the default remains lzjb.
Similarly lz4 is now the preferred method for compressing meta data
when available.

* The use of mkdir/rmdir/mv in the .zfs/snapshot directory has been
disabled by default both locally and via NFS clients. The
zfs_admin_snapshot module option can be used to re-enable this
functionality.

* LBA weighting is automatically disabled on files and SSDs ensuring
the entire device is used fairly.
* iostat accounting on zvols running on kernels older than Linux 3.19
is no longer supported.

* The known issues preventing swap on zvols for Linux 3.9 and newer
kernels have been resolved. However, deadlocks are still possible for
older kernels.

Module Options

* Changed zfs_arc_c_min default from 4M to 32M to accommodate large
  blocks.
* Added metaslab_aliquot to control how many bytes are written to a
  top-level vdev before moving on to the next one. Increasing this may
  be helpful when using blocks larger than 1M.
* Added spa_slop_shift, see 'reserved space' comment in the 'changes
  to behavior' section.
* Added zfs_admin_snapshot, enable/disable the use of mkdir/rmdir/mv
  in .zfs/snapshot directory.
* Added zfs_arc_lotsfree_percent, throttle I/O when free system
  memory drops below this percentage.
* Added zfs_arc_num_sublists_per_state, used to allow more
  fine-grained locking.
* Added zfs_arc_p_min_shift, used to set a floor on arc_p.
* Added zfs_arc_sys_free, the target number of bytes the ARC should
  leave as free.
* Added zfs_dbgmsg_enable, used to enable the 'dbgmsg' kstat.
* Added zfs_dbgmsg_maxsize, sets the maximum size of the dbgmsg
  buffer.
* Added zfs_max_recordsize, used to control the maximum allowed
  record size.
* Added zfs_arc_meta_strategy, used to select the preferred ARC
  reclaim strategy.
* Removed metaslab_min_alloc_size, it was unused internally due to
  prior changes.
* Removed zfs_arc_memory_throttle_disable, replaced by
  zfs_arc_lotsfree_percent.
* Removed zvol_threads, zvols no longer require a dedicated task
  queue.
* See zfs-module-parameters(5) for complete details on available
  module options.

Bug Fixes

LU-6155 osd-zfs: dbuf_hold_impl() called without the lock

The osd-zfs osd_count_not_mapped() calls dbuf_hold_impl() without
the required lock. In addition, dbuf_hold_impl() is an internal
function and has the expensive side effect of reading the block
from disk which would convert a full-block write into a
read-modify-write.

Since space estimation with ZFS is complicated any way, just use
the worst case as a rough estimate where a snapshot holds all current
blocks, i.e. no old space can be freed after the COW.

Skip test sanity-quota/23 on ZFS because overwrites on ZFS are not
guarenteed to be space neutral, and new worst-case assumptions will
always cause this test to fail.

LU-2049 grant: delay grant releasing until commit

Grant space acquired for a bulk write is released from the grant
accounting at the end of request processing. At that point, the
additional space consumed by the write request is believed to be
taken into account in any subsequent statfs call.
However, it does not seem to be the case with all backend
filesystems and more particularly ZFS which seems to provide
reliable space information only once the transaction associated
with the bulk write has committed. This creates a hole in the
grant space management where we can end up allocating more grant
space than really available.

This patch postpones grant releasing until transaction commit time.
This is done by registering a commit callback in charge of this
operation.
The patch also removes the implicit use of info->fti_used and stores
the amount of grant space to be released in obdo::o_grant_used.

LU-6527 ext4: journal_commit_callback optimization

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-7179 scripts: init and ha script fixes

1) Because of a typo, Lustre.ha_v2 currently continues running after
determining that a bad resource-name has been provided by the user.

This commit fixes that typo so that die() is called when
the target-name is bad.

2) When a target is in recovery, lustre/scripts/lustre produces
improper output when run as follows, and a relevant target is in
recovery:

/etc/init.d/lustre status
/etc/init.d/lustre status local
/etc/init.d/lustre status foreign

A grep command in health_check() expects variables to contain the path
to /proc files containing recovery status, but these variables'
contents were altered in a prior commit.

LU-7190 lfsck: tolerate MDT-OST communication failures

During the 2nd phase scanning, the layout LFSCK slave engine on the
OST will query the master engine status from the MDT periodically.
Sometimes, the query RPC may hit failure that may because network
trouble, or the MDS node issues. To make the LFSCK can go ahead,
the slave engine will not wait for ever, instead, it will assume
the master engine has exited without notifying (or fail to notify)
the slave engine. So the slave engine will exit also and clean up
the LFSCK environment on the OST, including the OST-object access
bitmap that is used to find out orphan OST-objects.

On the other hand, the assumption of master engine exit maybe wrong.
If the master engine does not exit, and the network trouble between
the MDS and OSS recovered after the slave engine exited, then the
master engine will try to find out orphan OST-objects during its
2nd phase scanning. But because the slave engine has already exited
and released the OST-object access bitmap, the master engine has
no way to find out orphan OST-objects.

To avoid above trouble, we make some compromise: when the slave
engine on the OST failed to query the master engine status, it will
not exit at once, instead, it will try several times. If the network
trouble can recover during such interval, the LFSCK will go ahead;
otherwise, the slave engine will exit as original does.

LU-5951 ptlrpc: track unreplied requests

The request xid was used to make sure the ost object timestamps
being updated by the out of order setattr/punch/write requests
properly. However, this mechanism is broken by the multiple rcvd
slot feature, where we deferred the xid assignment from request
packing to request sending.

This patch moved back the xid assignment to request packing, and
the manner of finding lowest unreplied xid is changed from scan
sending & delay list to scan a unreplied requests list.

This patch also skipped packing the known replied XID in connect
and disconnect request, so that we can make sure the known replied
XID is increased only on both server & client side.

LU-6271 osc: further OSC cleanup after eviction

A few problems are fixed in this patch:
1. a ldlm lock could be canceled simutaneously by ldlm bl thread and
  cleanup_resource(). In this case, only one side will win the race
  and the other side should wait for the work to complete;
2. in lov_io_iter_init(), if cl_io_iter_init() against sub io fails,
  it should call cl_io_iter_fini() to cleanup leftover information;
3. define osc_lru_reserve() and osc_lru_unreserve() to reserve LRU
  slots in osc_io_write_iter_init() and unreserve them in fini();
4. eviction on group lock is well supported;
5. cleanups
