LU-3641 libcfs: Zero fill shrinker struct in cfs_set_shrinker

Dropping Lustre caches might not terminate if the Linux kernel
supports the customisable shrinker batch size feature (commit
e9299f5058595a655c3b207cda9635e28b9197e6). This kernel feature
added a new field (batch) to the shrinker struct. Lustre does
not initialize it. When the unitialized batch value is negative,
the kernel shrink_slab function never terminates its loop that
calls the Lustre shrinker function. The problem was observed
with the ldlm_pools_cli_shrink shrinker, but it could also happen
with other Lustre shrinkers.

The fix is to ensure that all fields of the shrinker struct are
initialized by zero filling the struct when cfs_set_shrinker
allocates it. Zero filling works with all versions of the kernel.

In fact it is expected to be NULL.  desc->bd_import is the correct

LU-3335 scrub: OI scrub on OST

OI scrub should has the ability to handle kinds of OI, including
both the OI files on MDT and the /O directory on OST.

We trust the FID in LMA for both MDT objects and OST objects. So
if some /O sub-item does not match related LMA, then the /O will
be updated, instead of the LMA.

To guarantee that the OI scrub can run without MDT0 involved for
FLDB, the OST object needs to store some flag in its LMA to tell
OI scrub that it is for an OST object, no need to query the MDT0.

LU-3544 nfs: writing to new files will return ENOENT

This happend with SLES11SP2 Lustre client, which in turn acts as an
NFS server, exporting a subtree of an Lustre fs through NFS.

We detected that whenever we are writing to a new file using, fx,
'echo blah > newfile', it will return ENOENT error. We found
out that this was caused by the anonymous dentry. In SLESS11SP2,
anonymous dentries are assigned '/' as the name, instead of an
empty string. When MDT handles the intent_open call, it will look
up the obj by the name if it is not an empty string, and thus
couldn't find it.

As MDS_OPEN_BY_FID is always set on this request, we never need
to send the name in this request.  The fid is already available
and should be used in case the file has been renamed.

LU-3264 tests: support failover testing with ZFS

This patch improves test-framework.sh to support failover testing with
ZFS under shared storage configuration.

After formatting a ZFS target, "cachefile=none" property will be set
on the ZFS storage pool so that the pool is not automatically imported
on system startup. And then the pool will be exported so as to leave
the import and export operations handled by mount_facet() and stop().

For SOFT failure mode (unmount and mount), "zpool export …" will be
run on the active server node to export the ZFS storage pool, and
"zpool import -f …" will be run on the failover partner node to import
the pool.

For HARD failure mode (power off and on), since the "cachefile=none"
property has been set on the ZFS storage pool on the active server
node, after the node is power-cycled, the pool will not be imported.
Then on the failover partner node, "zpool import -f …" can be run to
import the pool.

This is a reworked patch with fixes merged in.

LU-3093 lnet: Fix assert on empty group in selftest module

The core of the issue is that the selftest module doesn't sanitize its
own API, but it depends on lst utility to do such checks.  As a result
this issue manifests itself in this particular LU through an assert
on an empty group.  If the NID is misspelled then an empty group is
added.  An error output is provided, but if that's never checked in a
batch script, as is the case with this issue, then the script will try
to add an empty group to a test to run in a batch, and that will cause
an assert

The fix is two fold.  Ensure that lst utility checks that a group is
added with at least one node.  If not the group is subsequently
deleted.  And the add_test command would fail, since the group no
longer exists.

The second fix is to ensure that the kernel module itself sanitizes
its own API in this particular case, so that if a different utility is
used other than lst to communicate with the selftest kernel module
then this error would be caught.  This fix looks up the batch and the
groups, src and dst, in the ioctl handle and sanitizes that input at
this point.  If the group looked up either doesn't exist or doesn't
have at least one ACTIVE node, then the command fails.

NOTE:there are many other cases in the code where the selftest kernel
module doesn't check for sanity of the input, but depends totally on
the lst module to do such checks.  Particularly around length of
strings passed in.  Thus it is possible to crash the selftest module
if someone tries to create another userspace app to communicate with
the selftest kernel module without ensuring sanity of the params sent
to the kernel module.  In effect, it's always assumed that lst is the
front end for selftest and no other front end is to be used.

LU-2919 hsm: Implementation of exclusive open

In this patch, a framework of lease is implemented. However,
only exclusive lease is supported right now.

To apply a lease, MDS_OPEN_LEASE must be set to open the file, EX
mode open lock is returned to the client side to hold a lease. From
that time on, if this file is opened again by other processes, the
open lock will be revoked so the client who holds the lease will
know the lease is already broken by checking that open lock.

To release a lease, normal close is used. The client will revoke the
open lock before sending CLOSE request.

Lease can be applied in two ways. ll_lease_open()/close() can be
called directly if the lease holder is in kernel space; or if the
lease holder lives in user space, it has to open the file first and
then use ioctl() with command LL_IOC_SET_LEASE to apply a lease. The
lease holder has to poll the lease status itself.

LU-3568 contrib: ignore initial comments

LU-2800 autoconf: remove obsolete autoconf options

This commit combines 53 previous commits that only remove tests and
the corresponding dead code. The only exceptions are whitespace
removal in lustre/autoconf/lustre-core.m4 and removal of dead code
shrinking an if/else in lustre/llite/dir.c.

Summary follows:

autoconf: remove d_rehash_cond and __d_rehash tests

- d_rehash_cond and __d_rehash were never exported in a mainline
  release.

  them either.

- LC_TASK_CLENV_STORE checks to see if task_struct->tux_info exists.

- That was only the case on RHEL5, so we can drop it. The rest of the
  code is untouched since liblustre uses the same infrastructure.

  removed since v2.6.23.

LU-3483 llite: Null deref in ll_revalidate_nd on NFSmount

In calls to ll_revalidate_nd, the nameidata pointer nd is
sometimes null.  The core code of the function tests for
this case and handles it by calling ll_node_revalidate_it.
However, immediately before that code, there is a test to
see if the LOOKUP_RCU flag is set in nd->flags.  This test
does NOT check to see if the nd pointer is null.  Per
the comment, LOOKUP_RCU was added in kernel 2.6.38, and
this code is #ifdefed accordingly.
The fix is to test if nd is null in the LOOKUP_RCU check.

LU-3484 llite: Anonymous dentry incorrectly identified as root

When exporting Lustre via NFS on SLES11SP2, this check incorrectly identifies
anonymous dentries as root dentries.  This is due to a change in SLES11SP2
which makes the d_name.name for anonymous dentries the same as that for root
dentries.  (Details in LU-3484.)

This changes the check to directly compare the value of the dentry pointer
to the root dentry pointer found in the superblock, rather than using the name.
