Subject: [PATCH 14/16] mmc: stop abusing the request queue_lock pointer
Date: Wed, 14 Nov 2018 17:02:17 +0100	[thread overview]
Message-ID: <20181114160219.28328-15-hch@lst.de> (raw)
In-Reply-To: <20181114160219.28328-1-hch@lst.de>

mmc uses the block layer struct request pointer to indirect their own
lock to the mmc_queue structure, given that the original lock isn't
reachable outside of block.c.  Add a lock pointer to struct mmc_queue
instead and stop overriding the block layer lock which protects fields
entirely separate from the mmc use.
