This series fixes a race condition in blk-crypto keyslot management and makes some related cleanups. It replaces "[PATCH] blk-crypto: make blk_crypto_evict_key() always try to evict" (https://lore.kernel.org/r/20230226203816.207449-1-ebiggers@xxxxxxxxxx), which was a simpler fix but didn't fix the keyslot reference counting to work as expected. Changed in v2: - Call blk_crypto_rq_put_keyslot() when requests are merged - Add and use blk_crypto_rq_has_keyslot() - Add patch "blk-crypto: drop the NULL check from blk_crypto_put_keyslot()" Eric Biggers (4): blk-mq: release crypto keyslot before reporting I/O complete blk-crypto: make blk_crypto_evict_key() more robust blk-crypto: remove blk_crypto_insert_cloned_request() blk-crypto: drop the NULL check from blk_crypto_put_keyslot() Documentation/block/inline-encryption.rst | 3 +- block/blk-crypto-internal.h | 38 +++++++------- block/blk-crypto-profile.c | 64 ++++++++--------------- block/blk-crypto.c | 47 +++++++++-------- block/blk-merge.c | 2 + block/blk-mq.c | 17 +++++- 6 files changed, 87 insertions(+), 84 deletions(-) base-commit: 63355b9884b3d1677de6bd1517cd2b8a9bf53978 -- 2.39.2
