Merge tag 'for-5.5/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 to disallow stacking request-based DM on partitions. - Fix DM raid target to properly resync raidset even if bitmap needed additional pages. - Fix DM crypt performance regression due to use of WQ_HIGHPRI for the IO and crypt workqueues. - Fix DM integrity metadata layout that was aligned on 128K boundary rather than the intended 4K boundary (removes 124K of wasted space for each metadata block). - Improve the DM thin, cache and clone targets to use spin_lock_irq rather than spin_lock_irqsave where possible. - Fix DM thin single thread performance that was lost due to needless workqueue wakeups. - Fix DM zoned target performance that was lost due to excessive backing device checks. - Add ability to trigger write failure with the DM dust test target. - Fix whitespace indentation in drivers/md/Kconfig. - Various smalls fixes and cleanups (e.g. use struct_size, fix uninitialized variable, variable renames, etc). * tag 'for-5.5/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (22 commits) Revert "dm crypt: use WQ_HIGHPRI for the IO and crypt workqueues" dm: Fix Kconfig indentation dm thin: wakeup worker only when deferred bios exist dm integrity: fix excessive alignment of metadata runs dm raid: Remove unnecessary negation of a shift in raid10_format_to_md_layout dm zoned: reduce overhead of backing device checks dm dust: add limited write failure mode dm dust: change ret to r in dust_map_read and dust_map dm dust: change result vars to r dm cache: replace spin_lock_irqsave with spin_lock_irq dm bio prison: replace spin_lock_irqsave with spin_lock_irq dm thin: replace spin_lock_irqsave with spin_lock_irq dm clone: add bucket_lock_irq/bucket_unlock_irq helpers dm clone: replace spin_lock_irqsave with spin_lock_irq dm writecache: handle REQ_FUA dm writecache: fix uninitialized variable warning dm stripe: use struct_size() in kmalloc() dm raid: streamline rs_get_progress() and its raid_status() caller side dm raid: simplify rs_setup_recovery call chain dm raid: to ensure resynchronization, perform raid set grow in preresume ...
