Subject: [PATCH v2 0/7] dm-verity: FEC optimizations and fixes

Various optimizations and fixes for dm-verity's forward error
correction.  Targeting linux-dm/for-next and based on v6.19-rc1.

Changed in v2:
- Removed DM_VERITY_FEC_BUF_PREALLOC
- Made __verity_fec_finish_io() set ->fec_io to NULL.  (Might as well.)
- Added Sami's Reviewed-by

Eric Biggers (7):
  dm-verity: move dm_verity_fec_io to mempool
  dm-verity: make dm_verity_fec_io::bufs variable-length
  dm-verity: remove unnecessary condition for verity_fec_finish_io()
  dm-verity: remove unnecessary ifdef around verity_fec_decode()
  dm-verity: make verity_fec_is_enabled() an inline function
  dm-verity: correctly handle dm_bufio_client_create() failure
  dm-verity: allow REED_SOLOMON to be 'm' if DM_VERITY is 'm'
