![]() 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJTmavIAAoJEMUj8QotnQNay/EIAJI6lEFlQK3gG830+Yaw1m2U 7mnnX/Rd/N6RnccyhmFqk7Xu0REM7gJEgWicTQjR58La2DKFi072N0mwgHgHfB8f 1oOvUKN5Nb/a1CmRcVzSO0sbYcJn9I1r+k0buqfFHivU68wuedG+MrVya3YzOjvC 63MQiu4+3icDprcToxn+etz75FhrFps5QAsS0cH6t1VZqFCGIzxqgUKgY8zGo1CH P9hkYpJhhJe2aDh4vlFvpFYVFXt9zPoR+MkqXFW6Dn9GbR36gGaldTwnyhapla4N XYHDEdETcTqm2srOM5wW+jD0p+Id9/Lmd5Ld5J2zyARCYn/EG/SDCbiaVqOxEnc= =tv1B -----END PGP SIGNATURE----- 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. .
