Updated to 2.6.12-rc2.
Several of these patches ought to be ready to go upstream.

NB If you're using snapshots, don't apply the snapshot patches in there yet!

Revision 2:
  Store bdev between freeze and thaw.
  
  From: Christoph Hellwig <hch at lst.de>

Revision 3:
  Make __unlock_fs() void.
  
  From: Christoph Hellwig <hch at lst.de>

Revision 4:
  Allow freeze_bdev() to return an error.
  
  From: Christoph Hellwig <hch at lst.de>

Revision 5:
  Handle __lock_fs error etc.
  
  From: Christoph Hellwig <hch at lst.de>

Revision 6:
  Tidy dm_suspend.
  
  From: Christoph Hellwig <hch at lst.de>

Revision 7:
  Handle writes to a snapshot-origin device that has been extended since
  the snapshot was taken.

Revision 8:
  More snapshot metadata reading into separate function.

Revision 9:
  Move snapshot metadata loading to happen when table is created instead
  of when device is resumed.  Origin writes don't trigger exceptions until
  snapshot table becomes active (when resume() is called on snapshot).
  
  NB This patch may break some existing LVM2 and EVMS operations.

Revision 10:
  Flakey.

Revision 11:
  dm-mpath.c needs to use a private workqueue (like other dm targets
  already do) to avoid interfering with users of the default workqueue.
