Hi Linus,
I rebased the DM tree ontop of linux-block.git's 'for-3.18/core' at the beginning of October because DM core now depends on the newly introduced bioset_create_nobvec() interface.
The following changes since commit d8f429e1669b9709f5b669aac9d734dbe0640891:
block: add bioset_create_nobvec() (2014-10-03 15:28:18 -0600)
are available in the git repository at:

dm log userspace: fix memory leak in dm_ulog_tfr_init failure path (2014-10-05 20:03:38 -0400)
Please pull, thanks. Mike
---------------------------------------------------------------- . fix DM's long-standing excessive use of memory by leveraging the new bioset_create_nobvec() interface when creating the DM's bioset
. fix a few bugs in dm-bufio and dm-log-userspace
. add DM core support for a DM multipath use-case that requires loading DM tables that contain devices that have failed (by allowing active and inactive DM tables to share dm_devs)
. add discard support to the DM raid target; like MD raid456 the user must opt-in to raid456 discard support be specifying the devices_handle_discard_safely=Y module param.
---------------------------------------------------------------- Alexey Khoroshilov (1): dm log userspace: fix memory leak in dm_ulog_tfr_init failure path
Benjamin Marzinski (2): dm mpath: stop queueing IO when no valid paths exist dm: allow active and inactive tables to share dm_devs
Heinz Mauelshagen (2): dm raid: add discard support for RAID levels 1 and 10 dm raid: add discard support for RAID levels 4, 5 and 6
Joe Thornber (1): dm bufio: update last_accessed when relinking a buffer
Junichi Nomura (2): dm: remove nr_iovecs parameter from alloc_tio() dm: use bioset_create_nobvec()
Mikulas Patocka (1): dm bufio: when done scanning return from __scan immediately
