LU-80 mds: use md_size supplied by client, repack reply

- mdt uses only client easize to pack reply buffer with the same
buffer sizes as client has.
- introduce reply growing, when packing reply the proper MD size
might be unknown so clients data is being used, but after request
processing the proper size may be bigger than client expects and
reply buffer must be re-packed.
- if server data doesn't fit in buffer then it allocates bigger
buffer instead of using reply message buffer.
- rename mdt_shrink_reply into mdt_fix_reply. It does shrink and/or
grow when needed. Upon growing the bigger MD is copied into new
reply.
- server unpacks ea attr size always in mdt_reint_record for all
operation, so it is available always in rr_eadatasize.

LU-1016 build: no sub-builds in sub-shells

The make program paradigm is to have command failures fail the make.
Invoking a failing "make" in a subshell will cause the subshell
to exit returning non-zero to the invoking shell.  However, the
invoking shell will *NOT* exit.  Therefore, to correctly use a
subshell in a make file scriptlet, use the following template:

  ( do-some-stuff ) || false

this will work as expected.  You want "false" instead of "exit 1"
in case make as been invoked with the "-i" ("--ignore-errors")
option.

WRT the code in question, there really is no need of even using
a subshell.  So this patch fixes two (related) things:

1.  the "for subdir in $(RPM_SUBDIR)" is now done in one process
    and will cause the superior make to stop if any subdirectory
    make fails.

2.  The tests for BUILD_TESTS and BUILD_SERVER for building RPMs
    need to take into account the possibility that these are not
    necessarily defined in all autoMakefile.am's that use the
    autoMakefile.am.toplevel file.

LU-433 ldiskfs: remove jbd2-jcberr patch from kernel

Remove the AC_MSG_ERROR for kernels which don't export either
the jbd2_journal_callback_set or journal_callback_set symbols.
These are no longer required if your building against ext4
and thus should not cause a failure at configure time.

LU-611 utils: lfs find --stripe-{count,size,index}

Add options to "lfs find" so it can find files by their stripe-count,
stripe-index, and stripe-size. For stripe-index (alias ost-index) it

short options for these consistent between "lfs find", "lfs getstripe"
and "lfs setstripe", keeping the old options for usage compatibility.

Add a verbose deprecation for "lfs {get,set}stripe --offset" (which
is too vague a term) and suggest "lfs {get,set}stripe --index",
which existed since Lustre 1.8.1 and can be used for interop tests.
The prefered long-term option name is --stripe-index, but this is not
available in Lustre 1.8.x and would break interop tests.

Remove deprecated "-v", "-q", and "-r" options from "lfs find".  These
are holdovers from when "lfs find" and "lfs getstripe" were the same
command, and have been verbosely deprecated since the 1.6.4 release.

Originally, it is done in "lov_lock_unuse()" against toplock.
But osc_lock upcall() is against sublock. So the sublock state
may be un-updated and inconsistent with the low layer osc_lock
state, then causes the sublock cannot be cached.

On the other hand, cl_lock::cll_descr::cld_enq_flags should not be
changed during unuse() for passing parameter, as the replacement,
it can be done through cl_lock::cll_flags.

than begin a new series and allow auster to begin at a selected

auster has a new switch '-S suite-name' which allows the caller to

The idea behind all of this is that a test session that fails at a
