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@kernel.org),
which was a simpler fix but didn't fix the keyslot reference counting to
work as expected.

Eric Biggers (3):
  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()
