Description: RPCs being resent when they shouldn't be
Details    : Some RPCs that should not be resent are being resent.  This
	     can cause inconsistencies in the RPC state machine.  Do not

Fix 2.4 kernel compile error introduced by 10866 landing (missing typecheck).

  import is disabled adminitratively

 - testing infrastructure to control order in which clients recover

 - workaround for cascading timeouts when failure of 1 server node causes
   failures of unrelated connections. this caused different problems. for
   example, lock cancel timeouts.

- landed on HEAD

Mostly fixes related to using failover MDSs along lmv. This is also related to active_ref handling, etc.

Also fixed the following:
* name of lproc entry where lustre upcall can be seen in error message if upcall is failed.
* removed --master option which was supposed to work along with lmv and now it is obsoleted.
* clanups and fixes both in lconf and lmc

b_cmobd_merge should not be used for any further development or testing!

cMD_PRE_CMD_SMASH are the relevant tags.

The pre-smashing contents of HEAD will be committed by yury into b_cmd as a
merge of the two branches.  These will be stabilized on b_cmd and eventually
landed onto HEAD.

Better handling for OST eviction.  Fixes for clearing the page cache,
imp_invalid handling, and improved import_event interface. Also
includes the tests and fixes added from 2732; one of those tests does
not yet passed so it is excepted for now.

Adds support for client-side write cache accounting via OST write credits
(grants).  There is not yet a "correction" algorithm for grants if they
get out of sync between the client and OST (OST can handle clients who think
they have grant but do not).  Peter had previously suggested that grants
should decay over time (faster on the clients than on the OSTs) so idle
nodes do not consume space they aren't using.

Use /proc/fs/lustre/osc/OSC*/cur_grant_bytes (and existing cur_dirty_bytes)
to check client-side cache values.

Includes lustre-side changes for lfsck support (create files with
specific objids, create specific objids on OSTs).

Also includes some changes to the testing scripts (local.sh, lov.sh, acc-sm)
so that they include a "client nid '*'" client and can be used for sanityN.sh
testing.  This has been put into the main acceptance-small.sh loop so that
sanityN.sh will be run on both single and multi-OST setups.

The principal change here is ptlrpc_connect_import and recovery are
merged and are now asynchronous and are run on ptlrpcd.

This branch also includes fixes for

  2477 (this was the initial bug)

  2355 recover for initial connections

  1934 (b_1934 was merged directly to b_recovery)

  1901 block all file creations until orphan recovery completes

  2423 client remove rq_connection from request struct

  2640 conf-sanity test_5, and proper cleanup in umount when
       cleanup log is not availale.

  2670 recovery timer race

  2532 mdc_close recovey bug

And few others that werent' filed.

r=phil

Make sure threads waiting for a completion callback are awoken when
the client is evicted. Also set LDLM_FL_CANCEL explicitely in
cleanup_resouces, so callers of ldmm_namespace_cleanup no
longer need to specify it.

Approved by Andreas Dilger.

Fix for bug 974, Also adds a test to check for OOM (modified script from
bug 1135), fixes to sanity.sh's test 45 to obtain a grant (closes 2387).

Disable some console messages from failed statfs(), reconnect
