Please pull from:

master.kernel.org:/pub/scm/linux/kernel/git/agk/linux-2.6-dm.git master

to get the following device-mapper patches for inclusion in 2.6.40.
There are some minor fixes and a small patchset that reduces kcopyd memory
requirements.

dm mpath: do not fail paths after integrity errors

Mike Snitzer (1):
dm table: allow targets to support discards internally

Mikulas Patocka (8):
dm kcopyd: avoid pointless job splitting
dm kcopyd: preallocate sub jobs to avoid deadlock
dm kcopyd: remove superfluous page allocation spinlock
dm kcopyd: add gfp parm to alloc_pl
dm kcopyd: alloc pages from the main page allocator
dm io: use fixed initial mempool size
dm kcopyd: reserve fewer pages
dm kcopyd: return client directly and not through a pointer

Milan Broz (1):
dm table: reject devices without request fns
