Adrian Hunter 26caddf274 mmc: block: Fix unsupported parallel dispatch of requests ... The mmc block driver does not support parallel dispatch of requests. In normal circumstances, all requests are anyway funneled through a single work item, so parallel dispatch never happens. However it can happen if there is no elevator. Fix that by detecting if a dispatch is in progress and returning busy (BLK_STS_RESOURCE) in that case Fixes: 81196976ed ("mmc: block: Add blk-mq support") Cc: stable@vger.kernel.org # v4.16+ Signed-off-by: Adrian Hunter <adrian.hunter@intel.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>		2018-08-21 16:12:41 +02:00
