commit 6b79a428c02769f2a11f8ae76bf866226d134887 upstream. Otherwise the journal_io_cache will leak if dm_register_target() fails. Cc: stable@vger.kernel.org Signed-off-by: Mike Snitzer Signed-off-by: Greg Kroah-Hartman

Pull device mapper updates from Mike Snitzer: - Fix DM cache target to free background tracker work items, otherwise slab BUG will occur when kmem_cache_destroy() is called. - Improve 2 of DM's shrinker names to reflect their use. - Fix the DM flakey target to not corrupt the zero page. Fix dm-flakey on 32-bit hughmem systems by using bvec_kmap_local instead of page_address. Also, fix logic used when imposing the "corrupt_bio_byte" feature. - Stop using WQ_UNBOUND for DM verity target's verify_wq because it causes significant Android latencies on ARM64 (and doesn't show real benefit on other architectures). - Add negative check to catch simple case of a DM table referencing itself. More complex scenarios that use intermediate devices to self-reference still need to be avoided/handled in userspace. - Fix DM core's resize to only send one uevent instead of two. This fixes a race with udev, that if udev wins, will cause udev to miss uevents (which caused premature unmount attempts by systemd). - Add cond_resched() to workqueue functions in DM core, dn-thin and dm-cache so that their loops aren't the cause of unintended cpu scheduling fairness issues. - Fix all of DM's checkpatch errors and warnings (famous last words). Various other small cleanups. * tag 'for-6.3/dm-changes' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: (62 commits) dm: remove unnecessary (void*) conversion in event_callback() dm ioctl: remove unnecessary check when using dm_get_mdptr() dm ioctl: assert _hash_lock is held in __hash_remove dm cache: add cond_resched() to various workqueue loops dm thin: add cond_resched() to various workqueue loops dm: add cond_resched() to dm_wq_requeue_work() dm: add cond_resched() to dm_wq_work() dm sysfs: make kobj_type structure constant dm: update targets using system workqueues to use a local workqueue dm: remove flush_scheduled_work() during local_exit() dm clone: prefer kvmalloc_array() dm: declare variables static when sensible dm: fix suspect indent whitespace dm ioctl: prefer strscpy() instead of strlcpy() dm: avoid void function return statements dm integrity: change macros min/max() -> min_t/max_t where appropriate dm: fix use of sizeof() macro dm: avoid 'do {} while(0)' loop in single statement macros dm log: avoid multiple line dereference dm log: avoid trailing semicolon in macro ...
