- dozens and dozens of fixes for working with 2.6 kernels
 - new 2.4 kernel APIs
 - uncountable bug fixes

* bug fixes
 - Fix ldlm_lock_match on the MDS to avoid matching remote locks (592)
 - Fix fsfilt_extN_readpage() to read a full page of directory
   entries, or fake the remainder if PAGE_SIZE != blocksize (500)
 - Avoid extra mdc_getattr() in ll_intent_lock when possible (534, 604)
 - Fix imbalanced LOV object allocation and out-of-bound access (469)
 - Most intent operations were removed, in favour of a new RPC mode
   that does a single RPC to the server and bypasses most of the VFS
 - All LDLM resource ID arrays were removed in favour of ldlm_res_id
 - Aggressively cancel local locks on DLM servers
 - mds_reint_unlink sends EA to the client if it's the last nlink.
   client uses that EA to unlink OST objects.
 - mds_reint_{rename,unlink,link} were rewritten to take ordered locks
 - recursive symlinks were fixed (440)
 - fixed NULL deref in DEBUG_REQ
 - filter_update_lastobjid no longer calls sync, which annoyed extN
 - fixed multi-client small-writes to a single file problem (445)
 - fixed mtime updates during file writes (607)
 - fixed vector writes on obdfilter causing problems when ENOSPC (670)
 - fixed bug in obd_brw_read/write() (under guise of testing 367)
 - fixed Linux OST size reporting problem (444, 656)
 - OST now updates object mtime with writes or setattr (607, 619)
 - client verifies file size before zeroing page past EOF (445)
 - OST now writes last allocated objid to disk with allocation (108)
 - LOV on echo now works (409)
 * protocol changes
 - mds_reint_unlink sends a new buffer, with the EA included.  this
   buffer is only valid if body->valid & OBD_MD_FLEASIZE, which is only
   set if a regular file was being unlinked, and it was the last link
 - use PtlGet from the target for bulk writes (315)
 - OST now updates object mtime with writes or setattr (607, 619)
 - LDLM now has a grant-time callback to revalidate locked items, if
   necessary (604)
 - Many MDS operations were reorganized to combat race conditions
* other changes
 - Merge b_intel branch (updated lprocfs code) - now at /proc/fs/lustre
 - configure check to avoid gcc version 2.96 20000731-2.96-98 (606)

- fixes of many metadata bugs:
  - multiple client file opens
  - missing/extra intent releases
  - symlink fixes
- OST/MDS server threads clobbering each other
  - dbench 2 works mostly
- many others too numerous to mention here (ChangeLog is a good record)

- fix dentry->d_it clobbering
- credentials weren't being shipped for readdir/getattr operations
- remove invalid assertions triggered during some concurrent MD updates
- many, many updates to llanalyse

- dlm cleanups, bugfixes
- there are now two totally separate DLM callback packets and functions
- beginnings of ldlm /proc bits
- the lock server can now change the lock mode, in addition to the resource
- fix one part of the open() object creation race by adding a semaphore that's
  taken in ll_file_open
- some cleanup in obdclass/proc_lustre.c; much more is needed

- fixed userspace build problem in lustre_lib.h
- added intent-based lookup code
- fixed intent-based setattr
- added mds_fid2locked_dentry and mds_name2locked_dentry helpers
- don't crash in ptlrpc_reply, just warn of API violation
- update create.pl to open instead of mcreate

very gracefully.  Since there are races that make invalid handles not hugely
uncommon, that's fixed now.
- Even on the client side, we could get cancelled between ldlm_lock_decref() and
ldlm_lock_cancel(), thus passing an invalid handle into cancel().  This is
handled now.
- Fixed another leaked request.
- Fixed an IT_SETATTR bug, even though we don't currently exercise that code
path.
- Fixed common.sh for the multiple mount cleanup case
- llcleanup.sh was unloading things in the wrong order (MDS is pinned by LDLM
and needs to be unloaded later in the process).  Fixed.

- fixed the error handling paths of unlink and rmdir, so that unlinking a
non-existant file returns an error
- fixed the DLM bug that caused the perl script to hang (there's a new bug now
  that it triggers under heavier load that causes it to crash)
- fixed a second crashing bug that occurred if a blocked lock gets completed
  and then cancelled all before the server-side enqueue finishes (amazing but
  true)
- osc_open() now returns the actual rc instead of 0
- fixed a race condition in ptlrpc/service.c related to thread shutdown (nice
  catch, Mike)
