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

- remove extN/ files

Fixes a _huge_ number of bugs:
  - Fully reactivate OST imports after reconnection (512, others)
  - Make sure client sees our -ENOTCONN from mds_handle (513 - partial)
  - More graceful error handling for truncating on dead OST (515)
  - Don't error out unless we're actually accessing dead stripes (474)
  - Fix garbage sizes when stripes are missing (410)
  - LRU counters were broken, causing constant lock purge (433, 432)
  - garbage on read from stripes with failed OSTs (441)
  - mark OSCs as active before reconnecting during recovery (438)
  - lov_enqueue and lov_cancel need to handle inactive OSTs (403)
  - lfind did not preserve OST order in output (443)
  - symlinks cause hung clients, incorrect data (439)
  - stop dereferencing request after dropping refcount (457)
  - don't LASSERT(spin_is_locked) on non-SMP (455)
  - fixes for many rename() bugs
  - fstat didn't correctly synchronize attributes (399)
  - server must handle lock cancellation during blocking AST prep (487)
  - bulk descriptors were free()d too soon (511)
  - fix paths in lconf, which would load incorrect modules (451, 507)
  - fix confusing lconf 'host not found' error message (386)
  - fix lock order deadlock on OST (O/R i_sem before journal ops, 478)
  - fix race condition in mdc_blocking_ast() for inode access (526)
  - fix lov_unpackmd() unpacking wrong number of stripes (537)
  - fix lov_set_osc_active() marking wrong OSC inactive (440)
  - fix bad lstripe lov_unpackmd() assertion (fix layering too) (527)
  - fix multiple writes of stripe MD to MDS (358, maybe 519)
  - fix lstripe in several ways (kernel side) (527)
  - fix request leak in ldlm_cli_enqueue (262)
  - incorrect OSC was marked inactive after OST failure
  - call mds_fs_cleanup before unmounting filesystem (524)
  - fix races between taking ns_lock and ldlm_lock_change_resource
  - fix races updating LOV export open file list
  - fix lov_enqueue error path, avoid decref-ing bad lock handle
  - fix recovery NULL deref in ldlm_cli_cancel_unused
  - fix some DLM races by using new hash table for lock handles (419)
  - permit the client to specify desired inodes, at replay
  - duplicate requests when we queue them for replay reintegration
  - fix last_rcvd offset calculation
  - sync after each recovered transaction, so we always make progress
  - never, not always, ERESTART requests without transnos
  - store the lov_desc in the MDS, so we don't depend on getlovinfo to set it
  - skip replay if the MDS says that the client is already connected
  - don't check for a recovery-enabled export to match lctl's UUID
  - don't INC_USE_COUNT for phantom exports
  - don't crash when cleaning up phantom exports (567)
  - don't double-finish or set replay data for errored mdc_open requests
  - abort requests when they time out, so we don't get old replies
  - send/receive replies for AST messages again
  - if the client says that it doesn't have the lock, cancel it on the server
  - if we timeout during I/O, don't try to cancel an in-use lock; instead
    mark it as destroyed, it will all work out when decref is called
  - fix module use counts (22, 581)
 * protocol changes
  - ASTs now expect a reply (server cancels lock on error reply)

* and assorted cleanups

- 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)

landing b_brw, which _includes_ all fixes from b_lov.

Roughly, this fixes bugs in 3 general areas:

- OSC was locking one byte too many; fixed.

- several LOV bug fixes, to support adding LOVs and striping over fewer
  than the maximum number

- the brw code was rewritten

See the bugs listed above for more details.  This will be immediately
tagged as 0.5.17.

Also update runtests to do setup and cleanup with an XML file as a parameter.
Allow the llecho.sh script to build a config that will run on two separate
hosts if desired.

* llechocleanup.sh added for completeness
* small changes to tools to support llecho.sh

Convert scripts over to new setup methods where possible to avoid them
becoming increasingly outdated.  Some scripts are already broken, and
I don't use them so I'm not sure whether to remove them or fix them.

Scripts updated are llmount.sh, llrmount.sh, llecho.sh, lldlm.sh,
llmount-client.sh and llmount-server.sh.  They use the default config
scripts net*.cfg, obd*.cfg, ldlm.cfg, mds.cfg as needed to do the same
thing they used to do.

- removed request->rq_lock (never used)
- made a ptlrpc_thread structure, and a list of those in ptlrpc_service
- adapted service code to support multithreading
- removed service->srv_id (duplicated existing local_id)
- updated llecho

 - add a fail function to common.sh to notify user that umount failed

- give all attaches a name.
- clean up llmountcleanup.sh with name2dev
- remove debugging printouts from obdctl

	- make the NAL module conditional upon the network connection type.
	- rename setup() to be setup_lustre().
all others:
	- you need to call setup_portals() before setup_lustre() now.

- BUG -> LBUG to work with the crashdump tools

- lock the service structure whenever it mucks with state
- add full debugging to llecho.sh

- refactored request freeing code to handle the use of the reply buffer after
  the mdc_getattr, etc. returns.

unload 'obdecho'

- numerous small fixes to obdclass -- yippeah Andreas is back
- test_getattr (jt_multi_getattr) tells obdctl to fire many getattr requests.
- build this code, run obd/tests/llecho.sh and play with it

Avert your eyes.

include/linux/lustre_net.h: set the LUSTRE_NAL back to socknal
include/linux/class_obd.h: added full license boilerplate, #define cleanup
include/linux/obd_osc: there was some confusion with obd_ost; fixed.

- added bits to structures for ost_request
- added OSC/OST portals communication
- added osc_setattr()
- added rpc_unregister_service in an attempt to get a handle on cleanup
- brought tests/ostreq.sh into the 1990s
- fixed a trivial obdctl setattr bug

 lib/obd_pack.c - routines for packing/unpacking of OST requests
 lib/mds_pack.c - fixes (should be 64bit safe now)
 autogen.sh - no more Makefile.in in CVS
 tests/testreq.c tests/umreq.sh tests of the RPC infrastructure
