Subject: [PATCH] dm integrity: call kmem_cache_destroy() in
 dm_integrity_init() error path
References: bsc#1012628
Patch-mainline: 6.3.2
Git-commit: 6b79a428c02769f2a11f8ae76bf866226d134887

commit 6b79a428c02769f2a11f8ae76bf866226d134887 upstream.

Otherwise the journal_io_cache will leak if dm_register_target() fails.
