b_cmobd_merge should not be used for any further development or testing!

cMD_PRE_CMD_SMASH are the relevant tags.

The pre-smashing contents of HEAD will be committed by yury into b_cmd as a
merge of the two branches.  These will be stabilized on b_cmd and eventually
landed onto HEAD.

 - 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)

- 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)

- dramatically reorganized and simplified the headers.  Most of the nasty
  recursive definitions are gone, and obd_class.h no longer drags in the
  entirety of Lustre.
- .cvsignores updated and cleaned
- added another chunk of DLM code and a test, which passes (note that it doesn't
  free the locks yet, so don't expect to cleanup afterwards)
- fixed OBD_ALLOC/OBD_FREE in the same ways as the Portals macros
- removed a lot of dead obd_class code
