unlikely case that a DM device is created without a DM table and then accessed due to upper-layer userspace code or user error. - Fix DM thin-provisioning's metadata_pre_commit_callback to not use memory after it is free'd. Also refactor code to disallow changing the thin-pool's data device once in use -- doing so guarantees smae lifetime of pool's data device relative to the pool metadata. - Fix DM space maps used by DM thinp and DM cache to avoid reuse of a already used block. This race was identified with extremely heavy snapshot use in the context of DM thin provisioning. - Fix DM raid's table status relative to an active rebuild. - Fix DM crypt to use GFP_NOIO rather than GFP_NOFS in call to skcipher_request_alloc(). Also fix benbi IV constructor crash if used in authenticated mode. - Add DM crypt support for Elephant diffuser to allow for Bitlocker compatibility. - Fix DM verity target to not prefetch hash blocks for data that has already been verified. - Fix DM writecache's incorrect flush sequence during commit when in SSD mode. - Improve DM writecache's sequential write performance on SSDs. - Add DM zoned target support for zone sizes smaller than 128MiB. - Add DM multipath 'queue_if_no_path_timeout_secs' module param to allow timeout if path isn't reinstated. This allows users a kernel safety-net against IO hanging indefinitely, due to no active paths, that has historically only been provided by multipathd userspace. - Various DM code cleanups to use true/false rather than 1/0, a variable rename in dm-dust, and fix for a math error in comment for DM thin metadata's ondisk format. -----BEGIN PGP SIGNATURE----- iQFHBAABCAAxFiEEJfWUX4UqZ4x1O2wixSPxCi2dA1oFAl4xvEITHHNuaXR6ZXJA cmVkaGF0LmNvbQAKCRDFI/EKLZ0DWipYCAC+sX8q/XBDRi4WDCTvCRCcBfz9g9ZO oygimV64oYf08JiDL54Z29T0EjwGR6DcZB0nEyjhl2/lU4bPwd4kLc/VHwjf44ay oUJWZxp8Az7pIWjQQ5oC09it8gLmDpBdq2Z146tEDgYrERnH8BgDObYm3ihXwi9f zMoET8rIzNltMUo6jIumjzxPcLbBsRTnC35mE//PZkMiUUI3ucNWuOhD/ICDe/Tu VQ9rNtJx01xs07bFKT4OYR2Oc7xrtWEOMDKeSFz16j8t28wywLFz3EPXRG7tKM3l 6CKBFdRqPSL6v2Mr1QD8YwJJCPLsCoOQ14aKn2sDPG8EgQMnh7R2g6OT =mfnM -----END PGP SIGNATURE----- Merge tag 'for-5.6/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm Pull device mapper updates from Mike Snitzer: - Fix DM core's potential for q->make_request_fn NULL pointer in the unlikely case that a DM device is created without a DM table and then accessed due to upper-layer userspace code or user error. - Fix DM thin-provisioning's metadata_pre_commit_callback to not use memory after it is free'd.
