The current APIs, mmc_claim|release_host() doesn't play well when the mmc block device driver tries to convert to blk-mq. In principle we need a re-claiming possibility of the host from the mmc block device driver, and to know when to release the host, need to keep track of a reference count instead. This series, so far untested, implements the idea from above. Sent as an RFC just to get peoples opinion of whether this is an approach that could work.
