Merge tag 'dm-3.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper updates from Mike Snitzer: "This pull request is later than I'd have liked because I was waiting for some performance data to help finally justify sending the long-standing dm-crypt cpu scalability improvements upstream. Unfortunately we came up short, so those dm-crypt changes will continue to wait, but it seems we're not far off. . Add dm_accept_partial_bio interface to DM core to allow DM targets to only process a portion of a bio, the remainder being sent in the next bio. This enables the old dm snapshot-origin target to only split write bios on chunk boundaries, read bios are now sent to the origin device unchanged. . Add DM core support for disabling WRITE SAME if the underlying SCSI layer disables it due to command failure. . Reduce lock contention in DM's bio-prison. . A few small cleanups and fixes to dm-thin and dm-era" * tag 'dm-3.16-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm thin: update discard_granularity to reflect the thin-pool blocksize dm bio prison: implement per bucket locking in the dm_bio_prison hash table dm: remove symbol export for dm_set_device_limits dm: disable WRITE SAME if it fails dm era: check for a non-NULL metadata object before closing it dm thin: return ENOSPC instead of EIO when error_if_no_space enabled dm thin: cleanup noflush_work to use a proper completion dm snapshot: do not split read bios sent to snapshot-origin target dm snapshot: allocate a per-target structure for snapshot-origin target dm: introduce dm_accept_partial_bio dm: change sector_count member in clone_info from sector_t to unsigned
