LU-2800 autoconf: remove LC_SECURITY_PLUG test

Only the SLES 10 kernel took a vfsmount for various vfs operations
to support AppArmor before the path variants were available.
We can remove the test and the dead code.

LU-3768 tunefs: make tunefs.lustre work correctly for MGS

Since LDD_F_NEED_INDEX flag is unset for a stand-alone MGS during

"'----index' only valid for MDT,OST". To fix that, this patch is to

LU-2484 obd: add md_stats to MDC and LMV devices

Enable md_stats for MDC and LMV devices and fix the definition of
EXP_MD_COUNTER_INCREMENT() so that they will be tallied. These stats
track usage of the md_ops methods (from the OBD layer, not to be
confused with md_device methods) and are exported through the files
/proc/fs/lustre/{lmv,mdc}/*/md_stats.

Rename m_sync to m_fsync making the counter name (fsync) more
intuitive. Prune the minimally useful operations from set of md_ops to
be counted. The operations counted are close, create, enqueue,
getattr, intent_lock, link, rename, setattr, fsync, readpage, unlink,
setxattr, egtxattr, intent_getattr_async, and revalidate_lock.

Add assertions to lprocfs_counter_{add,sub}() to ensure that the
counter index lies in the appropriate range for stats. Remove the
corresponding assertions from OBD_COUNTER_INCREMENT(),
EXP_COUNTER_INCREMENT(), and EXP_MD_COUNTER_INCREMENT(). Add macros
NUM_OBD_STATS and NUM_MD_STATS for use when allocating stats.

In mdt_export_stats_init() allocate and initialize the nid_stats
member of struct exp_nid_stats using only the MDT private
counters. This does not affect the contents of
/proc/fs/lustre/mdt/*/exports/*/stats but does save memory.

Add a flag to struct obd_device to indicate if EXP_COUNTER_INCREMENT()
should increment stats in the nid_stats member (as in the case of OFD)
or not (MDT).

Remove the unused member exp_md_stats from struct obd_export.

When LU-1333 was landed, all HSM infrastructure was not yet landed and

Now, everything required is there and we should enable this

LU-3494 libcfs: Add relocation function to libcfs heap

When changing the values of the node in the heap which might affect
its ranking, we have to remove the node from the heap, change the
values and then insert the node into the heap again. The process of
inserting into the heap might fail because of memory insufficiency.
Sometimes, it is not convienient and efficient for a caller to handle
such kind of failure.

This patch adds a new function to do the job.

system against the size of the file before writing, but
the file stripe is never checked or set. So, test 101d
has failed with enough space on the file system to write
the file, but the default stripe was 1 and there was not
enough space on that single OST for the file.

before writing to the file system.
