[dm-devel] [PATCH v2 0/3] block: fix up bio_crypt_ctx allocation

[Eric Biggers]

This series makes allocation of encryption contexts either able to fail,
or explicitly require __GFP_DIRECT_RECLAIM (via WARN_ON_ONCE).

This applies to linux-block/for-next.

Changed since v1 (https://lkml.kernel.org/r/20200902051511.79821-1-ebiggers@kernel.org):
    - Added patches 2 and 3.
    - Added kerneldoc for bio_crypt_clone().
    - Adjusted commit message.

Eric Biggers (3):
  block: make bio_crypt_clone() able to fail
  block: make blk_crypto_rq_bio_prep() able to fail
  block: warn if !__GFP_DIRECT_RECLAIM in bio_crypt_set_ctx()
