*  Fixed obdecho persistent object size at 1 MByte.

*  Changed test_brw data verification tests to work on a fixed 4k block
   rather than on page size to allow different page sized servers and
   clients.

   forwarding interface from a single struct iovec for the message header +
   payload, to passing the message header by pointer, and the message body
   by ptl_kiov_t (== page,offset,size).  This restores portals router
   performance by allowing it to use socknal zero copy again.

*  Applied the socknal connection load balancing fix from Bug 2817

other places were still fixed).  NB: a lock on [x,y] protects a KMS of
up to y+1 bytes.

r Adilger

move defination IOC_MDC_GETSTRIPE and declaration op_create_file() to lustre_user.h cause it is needed for user-space apps.

add a funcation int get_file_stripe(char *path, struct lov_user_md *lum) in liblustreapi.c, which is used by user apps want to get Lustre files' stripe info

if mount.lustre is not installed, don't oops but print a message
suggesting it be checked.

land b_size on HEAD for 1.2

update smfs 1)Add kml in smfs, but still not finish it, will change later according to llog. 2)some minor fixs

r=phil

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.
b=2729

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.
