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.

Merge tag 'dm-3.18' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device-mapper updates from Mike Snitzer:
"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.
Summary:
- 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"

dm bufio: update last_accessed when relinking a buffer
dm raid: add discard support for RAID levels 4, 5 and 6
dm raid: add discard support for RAID levels 1 and 10
dm: allow active and inactive tables to share dm_devs
dm mpath: stop queueing IO when no valid paths exist
dm: use bioset_create_nobvec()
dm: remove nr_iovecs parameter from alloc_tio()
