#     
#     Pull block fixes from Jens Axboe:
#     
#      - Revert the mq-deadline priority handling, it's causing serious
#        performance regressions. While experimental patches exists to fix
#        this up, it's too late to do so now. Revert it and re-do it properly
#        for 5.15 instead.
#     
#      - Fix a NULL vs IS_ERR() regression in this release (Dan)
#     
#      - Fix a mq-deadline accounting regression in this release (Bart)
#     
#      - Mark cryptoloop as deprecated. It's broken and dm-crypt fully
#        supports it, and it's actively intefering with loop. Plan on removal
#        for 5.16 (Christoph)
