[PATCH 5.15 363/371] dm integrity: call kmem_cache_destroy() in dm_integrity_init() error path

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Mike Snitzer <snitzer@xxxxxxxxxx>

commit 6b79a428c02769f2a11f8ae76bf866226d134887 upstream.

Otherwise the journal_io_cache will leak if dm_register_target() fails.
