dm-bufio's locking to allow increased concurrent IO -- particularly for read access for buffers already in dm-bufio's cache. - Also split dm-bio-prison-v1's spinlock and rbtree with comparable aim at improving concurrent IO (for the DM thinp target). - Both the dm-bufio and dm-bio-prison-v1 scaling of the number of locks and rbtrees used are managed by dm_num_hash_locks(). And the hash function used by both is dm_hash_locks_index(). - Allow DM targets to require DISCARD, WRITE_ZEROES and SECURE_ERASE to be split at the target specified boundary (in terms of max_discard_sectors, max_write_zeroes_sectors and max_secure_erase_sectors respectively). - DM verity error handling fix for check_at_most_once on FEC. - Update DM verity target to emit audit events on verification failure and more. - DM core ->io_hints improvements needed in support of new discard support that is added to the DM "zero" and "error" targets. - Fix missing kmem_cache_destroy() call in initialization error path of both the DM integrity and DM clone targets. - A couple fixes for DM flakey, also add "error_reads" feature. - Fix DM core's resume to not lock FS when the DM map is NULL; otherwise initial table load can race with FS mount that takes superblock's ->s_umount rw_semaphore. - Various small improvements to both DM core and DM targets. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmRGtWwACgkQxSPxCi2d A1pBqgf/W7op3/PdXBI+tlb7j05MEvMaZx0vz3l+qF36SMglaP1yZLZPiU9MCX2V Sm2t4p7VEn5gAxvmzqa0/pLINC7u/m1IW9O6y3qdOEFAgwJ2st+/yaDqgguN5kiA uOzecyDfR7n0WU5rkaO2EUneO7MrYweLR3IROFNFNHndl4bVJOafDcOJvmsI4YYe 5PIMHb+AGND+O2lIVOvSiPD6e85trcRWkr2X6DUYlllV3XEaBLke5MP1OAp+o/Y5 MFPfznnuiEvcFAzsBoDebC5j7RBQjHw12Bp8ltZV1ZFbdvluw9q1GD2/uyR5UolV jmerZXKThV7lRJYqilUmt74Rxl2JSg== =zPkM -----END PGP SIGNATURE----- Merge tag 'for-6.4/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Split dm-bufio's rw_semaphore and rbtree.
