With the rewrite of the Lustre quota code we no longer
need ll_quota_[on/off]. Those obsolete methods touched

Don't allow seq_proc_write_common() to specify arbitrary ranges,

Instead, limit the sequence range that can be written via /proc to
a subset of the sequence range currently allocated to that node.
Add the "clear" keyword to allow dropping the entire local sequence

device upgraded from lustre-1.8 and trigger full OI scrub to process
IGIF mapping into OI files.

continue to lustre-2.4, the such detect mechanism will be failed.

The new detect mechanism will combine the checking OI file name and OI
scrub successfully scan count: if there is old OI file "oi.16" and OI

LU-3249 tests: build POSIX test suite on FC18

While building POSIX test suite, some required header files are
not in the /usr/include directory on Fedora 18 distribution. On
FC18, only arm-gp2x-linux-glibc-2.3.6-11.fc18.noarch.rpm contains
those header files. This patch links those header files to the
standard system directory so as to make the building pass.

LU-2757 dynlocks: move into osd-ldiskfs

Commit 43603bd1 (LU-1548 osd: move i_htree_lock to iam container)
eliminated the use of dynlocks inside ldiskfs. Now that it's only
used in the osd-ldiskfs code, we can move it under osd-ldiskfs/,
and eliminate a patch we apply during build. Long term dynlocks
will never merged into the ext4 work so it makes sense to move it
to the osd-ldisk layer. Also the mdd layer was carrying techinical
debt of dynlocks as well so this patch removes it from that layer.
This work helps us move forward to a patchless ldiskfs in the
future.

LU-3669 xattr: separate ACL and XATTR caches

This patch separates ACL and XATTR caches, so that
when updating an ACL only LOOKUP lock is needed and
when updating another XATTR only XATTR lock is needed.

This patch also reverts XATTR cache support for setxattr
because client performing REINT under even PR lock
can deadlock if an active server operation (like unlink)
attempts to cancel all locks, and setxattr has to wait
for it (MDC max-in-flight is 1).

This patch also drops mot_xattr_sem because there is
no use case for FLXATTRLS with locking.

This patch also takes into account that osd_xattr_list
may be changing lu_buf, so it does not assume that
the buf is unchanged after the call.

This patch disables the r/o cache if the data is
unreasonably large (larger than maximum single EA
size).
