Merge tag 'dm-3.20-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull more device mapper changes from Mike Snitzer: - Significant dm-crypt CPU scalability performance improvements thanks to changes that enable effective use of an unbound workqueue across all available CPUs. A large battery of tests were performed to validate these changes, summary of results is available here: https://www.redhat.com/archives/dm-devel/2015-February/msg00106.html - A few additional stable fixes (to DM core, dm-snapshot and dm-mirror) and a small fix to the dm-space-map-disk. * tag 'dm-3.20-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm snapshot: fix a possible invalid memory access on unload dm: fix a race condition in dm_get_md dm crypt: sort writes dm crypt: add 'submit_from_crypt_cpus' option dm crypt: offload writes to thread dm crypt: remove unused io_pool and _crypt_io_pool dm crypt: avoid deadlock in mempools dm crypt: don't allocate pages for a partial request dm crypt: use unbound workqueue for request processing dm io: reject unsupported DISCARD requests with EOPNOTSUPP dm mirror: do not degrade the mirror on discard error dm space map disk: fix sm_disk_count_is_more_than_one()
