target destruction in DM targets: thin-pool, cache, integrity and clone. - Fix ABBA deadlocks in DM thin-pool and cache targets due to their use of a bufio client (that has a shrinker whose locking can cause the incorrect locking order). - Fix DM cache target to set its needs_check flag after first aborting the metadata (whereby using reset persistent-data objects to update the superblock with, otherwise the superblock update could be dropped due to aborting metadata). This was found with code-inspection when comparing with the equivalent in DM thinp code. - Fix DM thin-pool's presume to continue resuming the device even if the pool in is fail mode -- otherwise bios may never be failed up the IO stack (which will prevent resetting the thin-pool target via table reload) - Fix DM thin-pool's metadata to use proper btree root (from previous transaction) if metadata commit failed. - Add 'waitfor' module param to DM module (dm_mod) to allow dm-init to wait for the specified device before continuing with its DM target initialization. -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAmOXp8IACgkQxSPxCi2d A1rS2wf/VF82dcQpsAAT05L6j6xqo/eUe3Q3AZYbJGRl1Kg41NE/YRA1A/lsxykO j3wZut5UyL0ZEsjHhhUMC8rOeexfyqiecVdMofuQRkKJYa4l85IbPBE2qOMi/Ida WMsZg8bmm01hDPpZRUwj7L5BRDJlB0n9hdtkh16K0gboiaPZxmIEtum0IYr8krPj hOv6amx9MhrsiUcVWylFipmxTgpsxwwg67g2R6tCGUmHQhxHKFInvySrYdv5hYdy 3kr1pxy87Wn3oETrHNNc506qh6QK85mOC+D/VdNNzNnM6yhgOEkE9lSS/Er2rHyT D6Af4j5SIBy/srv5DjcWd7pi4NHIBA== =fuDb -----END PGP SIGNATURE----- Merge tag 'for-6.2/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Fix use-after-free races due to missing resource cleanup during DM target destruction in DM targets: thin-pool, cache, integrity and clone. - Fix ABBA deadlocks in DM thin-pool and cache targets due to their use of a bufio client (that has a shrinker whose locking can cause the incorrect locking order). - Fix DM cache target to set its needs_check flag after first aborting the metadata (whereby using reset persistent-data objects to update the superblock with, otherwise the superblock update could be dropped due to aborting metadata).
