tweaks. - Add journal support to the DM raid target to close the 'write hole' on raid 4/5/6. - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB. - Add 'metadata2' feature to dm-cache to separate the dirty bitset out from other cache metadata. This improves speed of shutting down a large cache device (which implies writing out dirty bits). - Fix a memory leak during dm-stats data structure destruction. - Fix a DM multipath round-robin path selector performance regression that was caused by less precise balancing across all paths. - Lastly, introduce a DM core fix for a long-standing DM snapshot deadlock that is rooted in the complexity of the device stack used in conjunction with block core maintaining bios on current->bio_list to manage recursion in generic_make_request(). A more comprehensive fix to block core (and its hook in the cpu scheduler) would be wonderful but this DM-specific fix is pragmatic considering how difficult it has been to make progress on a generic fix. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAABAgAGBQJYrJJeAAoJEMUj8QotnQNaDskIAIJeMX3Dc8Skt00tZ6vEj3p6 9juDpOrBKH3RYdqPmrYy9lVhhpFs6OoDfTQZaW/SmjDjHboJ3skKMjO+/NWav4nN 39LoDfxLbDi06fC7Y4H7FHUPjb5sKSzw4W5IttFEKmHOwkz+iwVFL1R0dihBqv7G Lq0Ta6xffW8jHrzpmmSDY1I6FSmZ9LlHPCL00qQ5Z7WkMS5oDk0GzZoLFasdNfvm fP9N13+uel2/R7hclpxE6J+IZPN5ARG3HAQ5POS+2gMlIzaH4AlMh7yf5q0sSGwq uQsmdps8c+LOtAakOzVScykEZvwBh+ci8VqE1X1zol+fl8ijeWqgWtz4XXYECC0= =saD8 -----END PGP SIGNATURE----- Merge tag 'dm-4.11-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Fix dm-raid transient device failure processing and other smaller tweaks. - Add journal support to the DM raid target to close the 'write hole' on raid 4/5/6. - Fix dm-cache corruption, due to rounding bug, when cache exceeds 2TB. - Add 'metadata2' feature to dm-cache to separate the dirty bitset out from other cache metadata.
