- b1_4 is basically the parent of HEAD, because that's the direction
  that changes flow, as strange as that sounds.  so there's a
  HEAD_BASE tag which sits on b1_4

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.

land b_cray_portals_merge on HEAD.  This consists of four families of changes:

1) Eric's work to change some APIs in Lustre's portals to come into line with
   Cray's portals and the spec.

2) add --with-cray-portals= to the build and use it to cut up the build
   when we're building lustre against external includes for Cray's portals.

3) Move some facilities from portals.o into libcfs.o so that Lustre can
   consume them when it is running against Cray's portals.o.

4) Fix up the liblustre build.  These changes have also made it to
   b_cray_delivery recently.

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.

Remove all orhpans on OST while MDS startup, and set last_id correctly.

        mechanical, plus a tiny Makefile.am cleanup in ptlrpc.

Set correct last object id when cleaning up orphans during mds setting up.
