LU-6458 mdd: try linkEA first in mdd_parent_fid

It should try to get parent FID from linkEA first, if that
fails, then do lookup dotdot. Two benefits

1. read EA is likely cheaper than lookup.

2. for striped directory, lookup might cause load sub stripes,
which is only necessary for certain operation (like unlink),
and for other cases, we should avoid it, because it will pin
the sub_stripe object with the master objet in the memory, i.e.
sub stripe object will only be freed when the master object
is freed, see lod_object_free()->lod_object_free_striping().

direct_IO: use iov_iter_rw() instead of rw everywhere

The rw parameter to direct_IO is redundant with iov_iter->type, and
treated slightly differently just about everywhere it's used: some users
do rw & WRITE, and others do rw == WRITE where they should be doing a
bitwise check. Simplify this with the new iov_iter_rw() helper, which
always returns either READ or WRITE.

LU-4840 lfs: Use file lease to implement migration

Implement non-blocking migration based on exclusive open instead of
group lock. Implemented exclusive close operation to atomically put
a lease, swap two layouts and close a file. This allows race-free
migrations.

Make the caller responsible for retrying on failure (EBUSY, EAGAIN)
in non-blocking mode.

In blocking mode, allow applications to trigger layout swaps using a
grouplock they already own, to prevent race conditions between the
actual data copy and the layout swap. Updated lfs accordingly. File
leases are also taken in blocking mode, so that lfs migrate can issue
a warning if an application attempts to open a file that is being
migrated and gets blocked.

Timestamps (atime/mtime) are set from userland, after the layout swap
is performed, to prevent conflicts with the grouplock.

lli_trunc_sem is taken/released in the vvp_io layer, under the DLM
lock. This re-ordering fixes the original issue between truncate and
migrate.

LU-6152 osd-zfs: ZFS large block compat

This patch adds the required compatibility code to leverage the
new ZFS large block feature.  This includes supporting older versions
of ZFS which not contain large block support (ZFS v0.6.3 and earlier).

At the heart of this change is the SPA_MAXBLOCKSIZE macro which has
been increased from 128K to 16M.  This macro has always defined the
maximum possible blocksize support by ZFS.  However, just because
the ZFS code may now support this new large block it doesn't mean
that the feature is enabled on the pool.  Therefore, all consumers
of SPA_MAXBLOCKSIZE have been changed to use spa_maxblocksize() which
consults the pools feature flags to determine the supported maximum.

In addition, the ZFS OSD has been updated to to properly integrate
with a datasets recordsize property.  This allows the maximum block
size of a dataset to be changed with the 'zfs set' command.  This
has no effect on existing objects but new objects will be written
using the larger block size.  For example:

  zfs set recordsize=1M <dataset>

Finally, all references to SPA_MAXBLOCKSIZE and SPA_MAXBLOCKSHIFT
were removed and replaced with portable equivilants.  Going forward
the OSD layer needs to take case to no longer make any assumtions
about the maximum block size.

LU-5939 hsm: make HSM modification requests replayable

There are several HSM requests which modify data on server and

LU-6477 build: Update SPL/ZFS to 0.6.4.1

Version 0.6.4 Relase Notes
https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.6.4

New Functionality

* Compatible with kernels up to Linux 4.0.
* New feature flags (additional details below):
        spacemap_histogram
        extensible_dataset
        bookmarks
        enabled_txg
        hole_birth
        embedded_data
* New asynchronous I/O (AIO) support.
* New fallocate() FALLOC_FL_PUNCH_HOLE support.
* New fragmentation metric in 'zpool list'.
* New LZ4 compression of meta data.
* New "redundant_metadata" property controls desired redundancy
level.
* New "overlay" property controls behavior for non-empty mount
points.
* New 'zpool list -v' shows individual disk capacity.
* New 'zpool get -H' (scripted mode) support.
* New 'zpool create -t' creates a pool with a temporary name.
* New arc_summary.py script from FreeNAS.
* New bash completion support.
* New DTRACE_PROBES integrated with Linux tracepoints.
* New compressed block histograms with zdb.
* New verbatim pool imports with zdb.

New Feature Flags

*   spacemap_histogram

    This features allows ZFS to maintain more information about how
free space is organized within the pool. If this feature is enabled,
ZFS will set this feature to active when a new space map object is
created or an existing space map is upgraded to the new format.

*   extensible_dataset

    This feature allows more flexible use of internal ZFS data
structures, and exists for other features to depend on. This feature
will be active when the first dependent feature uses it.

*   bookmarks

    This feature enables use of the zfs bookmark subcommand. Bookmarks
mark the point in time when a snapshot was created, they can be used
as the incremental source for a zfs send command. All bookmarks in the
pool can be listed by running zfs list -t bookmark -r poolname.

*   enabled_txg

    Once this feature is enabled ZFS records the transaction group
number in which new features are enabled. This has no user-visible
impact, but other features may depend on this feature.

*   hole_birth

    This feature improves performance of incremental sends ("zfs send
-i") and receives for objects with many holes. The most common case of
hole-filled objects is zvols.

*   embedded_data

    This feature improves the performance and compression ratio of
highly-compressible blocks. Blocks whose contents can compress to 112
bytes or smaller can take advantage of this feature.

    Fixed corruption during spacemap reallocation.

LU-6206 ptlrpc: start minimum service threads

If the ptlrpc_min_threads parameter is changed via /proc after the
service has started, then at least the requested number of service
threads should be started.  Otherwise this parameter would only be
used at initial thread startup and ignored if changed via /proc.

Fix conf-sanity.sh test_53[ab] to verify that at least the minimum
number of threads has been started when threads_min parameter is
changed, instead of just checking the parameter itself.  Also fix
test code style for 80-column line wrapping and tabs for indents.

The head utility does not always support shortcut "-1" option. It
should be specified as "-n1".

LU-6266 libcfs: add kstrtoul() compat function

The kstrtoul() function was only added to the upstream kernel in
commit v2.6.38-6934-g33ee3b2. While it is backported to RHEL6 2.6.32
kernels, it does not exist for vanilla kernels before that point.

The patch http://review.whamcloud.com/5700 added uses of kstrtoul()
to Lustre that break the build for older kernels.  While it would be
possible to convert those calls to simple_strtoul(), that function
is deprecated in newer kernels, and checkpatch.pl will generate a
warning, so using kstrtoul() is the right thing for newer kernels.

Add a wrapper function for kstrtoul() for older kernels.  There are
other kstrto*() functions in newer kernel not added by this patch.
Only the one function call is currently used, though it would be good
to convert Lustre over to using this family of functions instead of
simple_strtoul() in the future.
