Merge tag 'dm-3.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm
Pull device-mapper changes from Alasdair G Kergon:
"Remove the power-of-2 block size constraint on discards in dm thin
provisioning and factor the bio_prison code out into a separate module
(for sharing with the forthcoming cache target).
Use struct bio's front_pad to eliminate the use of one separate
mempool by bio-based devices.
A few other tiny clean-ups."
* tag 'dm-3.7-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/agk/linux-dm:
dm: store dm_target_io in bio front_pad
dm thin: move bio_prison code to separate module
dm thin: prepare to separate bio_prison code
dm thin: support discard with non power of two block size
dm persistent data: convert to use le32_add_cpu
dm: use ACCESS_ONCE for sysfs values
dm bufio: use list_move
dm mpath: fix check for null mpio in end_io fn
