* PtlMDUnlink() can no longer return PTL_MD_INUSE, since it commits the MD
for destruction. If no network I/O is current at the time, a
PTL_EVENT_UNLINK event is created.
* The 'unlinked_me' field of an event has been replaced by a simple flag
'unlinked' that is set if the event signals the destruction of the MD.
* Events have a new 'status' field. This is PTL_OK on successful
completion, and any other portals errno on completion with failure.
CWARN() messages in these callbacks log abnormal completion.
* All event callbacks changed to handle the UNLINK event, completion
status and unlinked flag.
* All abnormal completions changed to work with PltMDUnlink and the new
callbacks.
* Removed bd_complete from ptlrpc_bulk_desc and added bd_success.
Communications have completed when bd_network_rw gets cleared. If
bd_success is set, then bd_nob_transferred tells you how much data
was sent/received.
* Changed MDS and OST bulk completion to deal with failed bulk transfers.
The PtlBD server just LASSERTS things went OK, so we can be reminded to
implement better error handling there too.
* ptlrpc_wake_client_req() inline helper.
* Changed the lib/NAL interface as follows....
. cb_callback() is optional and defaults to calling the event queue's
callback if it is left NULL.
. cb_read(), cb_write(), cb_map(), cb_map_pages(), return PTL_OK on
success and another portals errno on failure.
. cb_send(), cb_send_pages(), cb_recv(), cb_recv_pages() return PTL_OK
if and only if they can commit to calling lib_finalize() when the
relevent message completes (possibly with error).
. cb_send(), cb_send_pages(), cb_recv(), cb_recv_pages() may not modify
the iovec/ptl_kiov_t they are passed, and must do I/O on the
subsection of this scatter/gather buffer starting at 'offset' for
'mlen' bytes. This greatly simplifies portals lib level descriptor
management at minimal expense to the NAL.
. portals lib now exports lib_extract_iov(), lib_extract_kiov() and the
other iov helpers take an additional 'offset' parameter, to simplify
offset buffer coding in the NAL.
. lib_parse() is void (i.e. returns no value).
. lib_finalize() takes an addition ptl_errno_t completion status.
...note that NALs other than qswnal and socknal need to have these
changes implemented properly and tested.
* Swapped some loose fprintf()s for CERROR()
* Dropped PORTAL_SLAB_ALLOC(); portals just uses PORTAL_ALLOC() now.
Since there are no slabs now, I also changed #ifdef PTL_USE_SLAB_CACHE
to #ifndef PTL_USE_LIB_FREELIST
* Changed lib_msg_alloc() so it is _never_ called with the statelock held,
just like all the other allocators.
* Changed dynamic MD allocation to size the MD by the number of fragments.
* Dropped a bunch of dross, plus the iovs from lib_msg_t so they become
tiny again.

Add new LOV EA format which gives us fields for features needed in the post
1.0 stage (e.g. RAID, OST migration/replacement) as well as more efficient
storage than the current layout when there are few stripes on lots of OSTs.
As well, we will now be able to back up/restore/manipulate EA data via the
"getfattr" and "setfattr" tools (attr RPM) that are part of EA tools from
the "trusted.lov" attribute (only accessible to root/priviledged users).
Also contains code to transparently migrate from old EA format to new one
the first time the EA is accessed. Note that there is no going back to old
code on the same filesystem once the EAs have been updated. EA conversion
is (hopefully) "fail safe" in that an error during conversion just means
that the on-disk EA is kept in old format (clients understand both because of
common code).
Some of the "compat" code can be removed once we hit 1.0 and users have
migrated, but the infrastructure itself should probably remain for the
next time we need to change the EA format.
This also adds "lustre_user.h" which was in b_llp_hp and has existed in
b_llnl for some time, but alas the user EA format had to change in order
to allow specification of striping format. A recompile should fix it.
Some minor warts remain:
- mds_objids_from_lmm() knows too much about lmm format. It had an existing
bug (looping to ld_tgt_count vs lmm_ost_count) and caused another bug for
me because it does its own unpacking of the lmm) and it would be nice to
just get rid of it and use obd_unpackmd(lmm) to get an lsm instead and use
that instead of "ids"
- need to fix up endianness from ll_lov_setstripe() because this is now not
done on the same host any more (object creation is done on MDS now)
- liblustreapi() should not be doing the printing of structs, but should
instead just return structs to user-space and/or using a callback function
supplied by the caller (e.g. for lfind iterating over filesystem). The
lov_dump_user_lmm* functions should probably be exported from the library
and be used as default print functions as a starting point.

Flesh out the async OBD IO API to be more user friendly. llite behaviour

we need to do something other than this anyway.)

Wait for dirty data to be handled (writeback, truncate, etc) before issueing
the mdc close. This is done by tracking opens for write and dirty data and
deferring mdc close at file_release if there aren't other opens for write and
there is dirty data. We perform these deferred closes when the dirty data is
taken care of or when another open for write comes along.
Also, a hot sanity test to verify the behaviour.

Fix for missing open flags for vfs_intent-2.4.20-rh kernel patch.
This change was also needed for the vfs_intent-2.4.20-hp patch. b=1877
Also add bug 1344 revalidate loop fixes to some of the vfs_intent patches.
The diff is fairly large, so that the files in the 2.4.20-rh patch are
in the same order as in all of the other vfs_intent patches to make
comparison and maintenance easier. Some other minor changes are made to
keep the patches consistent.
There is still a difference between vfs_intent-2.4.20-vanilla and -rh
in follow_down, but I don't know which one is the "keeper".
