/me raises eye-brows:

blk-cgroup.h          blkdev.h              blk-mq.h              blktrace_api.h
blk-crypto.h          blk-integrity.h       blkpg.h               blk_types.h
blk-crypto-profile.h  blk-mq-dma.h          blk-pm.h

What sort of mix-and-match bonanza have you got going on over there?
