In the upstream ext4 code there is a new functionality to allow a
per-commit callback to be set (j_commit_callback), which is used by

LU-553 build: Lustre style commit hooks for Git

Adds recommended commit hooks for Lustre commit messages, that
can/should be installed into lustre/.git/hooks for all Lustre trees.

prepare-commit-msg: adds the output of checkpatch.pl as a

    patch is matching the Lustre coding style. It doesn't check
    100% of the Lustre coding style, but at least finds most of
    the obvious errors so that they can be fixed locally before
    any manual inspection time is spent on the patch.

commit-msg: verifies the format of the commit message (somewhat).
    Checks that there is a valid-looking Signed-off-by: line.
    Adds the Gerrit Change-Id: line for change tracking.

LU-592 1.8 <-> 2.1 interop: missing LMV on client

When the cluster is upgraded from 1.8, client will not have LMV layer,
and the "ll_md_exp" is pointing to MDC directly, so the code which
assuming "ll_md_exp" as LMV need be revised:

- ll_dir_ioctl(LL_IOC_GETOBDCOUNT) should return 1 for MDC case;
- mdc_iocontrol() needs to handle the OBD_IOC_QUOTACTL as well when the
  "ll_md_exp" is MDC;

LU-455 Replace DIST_SOURCES with EXTRA_DIST

Resolve autoconf-2.63 warnings mainly by replacing DIST_SOURCES
with EXTRA_DIST.  Additionally, the non-portable $(shell) contruct
was removed from tests/module.mk and the sources simply enumated.
Finally, the incorrect EXTRA_SOURCES instance was removed from
the top level autoMakefile.am.

  Running automake-1.11 -a -c -W no-portability
  libcfs/libcfs/autoMakefile.am:92:
          variable `DIST_SOURCES' is defined but no program or
  libcfs/libcfs/autoMakefile.am:92:
          library has `DIST' as canonical name (possible typo)

  lnet/klnds/mxlnd/autoMakefile.am:44:
          library has `DIST' as canonical name (possible typo)
  ...

Also, as a result of the above changes, libcfs/libcfs/autoMakefile.am had to be
modified in order to allow 'make dist' to succeed.

As it turns out, libcfsutils_a_SOURCES was incorrect. That list contained
references to nonexistent 'util/[parser|platform].h' files. The assumption is
it intended to reference libcfs/include/libcfs/util/[parser|platform].h.

To fix the issue, both [parser|platform].h references were removed from the
list. This produces a simple solution that maintains consistency with the rest
of the build system. The caveat being that libcfsutil.a won't automatically be
rebuilt if either of the intended [parser|platform].h files are modified.

LU-407 Fix lustre-modules rpm name in spec file.

RHEL and Fedora kernels include ".%{_arch}" in the kernel's version
string.  Since Lustre includes the kernel version in its rpms, it
can appear that a double architecture name appears at the end.  Really
one is from the kernel, and one is from Lustre.  Trying to change that
is probably more trouble than it is worth.

This seems to cause problems with rpm's understanding of rpm names.  To
fix that this patch takes Andreas's suggestion of grep'ing the full
rpm name from "rpm -q kernel-modules".

We also add "|| true" to the last line of the %preun scriptlet so that
failure does not aport installation.

Finally, we also remove the redundant greps in the postun scriptlet.

This will also facilitate the compatibility handling for the 1.x

Also, check for LL_IOC_QUOTACTL in ll_dir_ioctl(), since this is the

LU-484 Don't do error cleanup in ext4_add_dot_dotdot()

The ext4_add_dot_dotdot() will do cleanup work (zeroing i_nlink, iput)
when ext4_bread() fails, that will mess up the i_nlink and i_count if
the ext4_add_dot_dotdot() is called from lustre.

The error cleanup work should be moved from ext4_add_dot_dotdot() to
it's caller: ext4_mkdir().

LU-464 obdfilter-survey test 2a ASSERT(imp->imp_sec == NULL)

There is a race in echo client:
1. `lctl --device $echo_client_dev detach`
     -> class_detach() puts last refcount of export
       -> obd_zombie_add_export() adds this export in zombie list, and
            wake up zombie thread.
2. zombie thread culls this export:
     class_destroy_export() put last refcount of echo_client_dev
       -> obd_cleanup()
         -> echo_device_free()
           -> echo_client_cleanup()
             -> osc_disconnect()
               -> client_disconnect_export() will clear cli->cl_import
3. `lctl --device $osc_dev cleanup`
     -> osc_precleanup() find scli->cl_import is not NULL (this means
          import is never connected, but it's not true here)
       -> class_destroy_import()
         -> class_import_put()
           -> LASSERT(imp->imp_sec == NULL) fails

It's expected that step 2 is done before step 3, but this can't be
guaranteed currently. To ensure this, osc_precleanup() calls
obd_zombie_barrier() to ensure step 2 is finished.

LU-5 readdir read multiple pages per rpc

add support for readdir to read multiple pages per rpc:
* because client has no idea how many directory pages it can read, it
  tries to read maximum pages each time, but will only store pages
  read from mds into page cache.
* add a flag LDF_COLLIDE to mark a dir page hash collides with the
  next page, and client will remove this page from page cache after
  processing.
* upon readpage bulk io failure, client won't be evicted, and client
  will resend the bulk request.
* support large page size on client: MDS_READPAGE RPC will fill reply
  with page size LU_PAGE_SIZE(4k), and if client page is bigger than
  LU_PAGE_SIZE, several pages will be integrated into one dir page with
  CFS_PAGE_SIZE.
