Revision 776e49e8ddb5169e6477fd33a396e9c7b2eb7400 authored by Linus Torvalds on 04 March 2020, 19:02:45 UTC, committed by Linus Torvalds on 04 March 2020, 19:02:45 UTC
Merge tag 'for-5.6/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm
Pull device mapper fixes from Mike Snitzer: - Fix request-based DM's congestion_fn and actually wire it up to the bdi. - Extend dm-bio-record to track additional struct bio members needed by DM integrity target. - Fix DM core to properly advertise that a device is suspended during unload (between the presuspend and postsuspend hooks). This change is a prereq for related DM integrity and DM writecache fixes. It elevates DM integrity's 'suspending' state tracking to DM core. - Four stable fixes for DM integrity target. - Fix crash in DM cache target due to incorrect work item cancelling. - Fix DM thin metadata lockdep warning that was introduced during 5.6 merge window. - Fix DM zoned target's chunk work refcounting that regressed during recent conversion to refcount_t. - Bump the minor version for DM core and all target versions that have seen interface changes or important fixes during the 5.6 cycle. * tag 'for-5.6/dm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm: bump version of core and various targets dm: fix congested_fn for request-based device dm integrity: use dm_bio_record and dm_bio_restore dm bio record: save/restore bi_end_io and bi_integrity dm zoned: Fix reference counter initial value of chunk works dm writecache: verify watermark during resume dm: report suspended device during destroy dm thin metadata: fix lockdep complaint dm cache: fix a crash due to incorrect work item cancelling dm integrity: fix invalid table returned due to argument count mismatch dm integrity: fix a deadlock due to offloading to an incorrect workqueue dm integrity: fix recalculation when moving from journal mode to bitmap mode
