if portals_nid2str() is used twice in a single printf-type thing it
will end up printing the same ip both times.

this patch adds a second buffer so that it prints the correct things.

 b 2074 comment 33 -- cleanup code using fstat()

Don't do precreate orphan recovery on an OST if the MDS is in recovery
mode. The OSC's last_id info is not initialized until after MDS
recovery is complete, so clearing the orphans here would result in
removing all the objects on the OST.

1. Replace i_mapping with the bottom inode imapping in mmap method according to peter's advice. 2. some minor fix

so we can remove max_rpcs_in_flight workaround on ALC.

Fix configure option indenting.

1. Adding iput(cache_inode) in smfs_clear_inode for clearing cache inode according to peter's advice. 2. other minor fixes in smfs_clear_inode

Andreas: I tested that OST will never grant more space to liblustre than
the initial 4M.

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.

get lconf to panic() when no host entry is found. using panic() will prevent
lconf from exiting cleanly when this happens.
