mmc: hsq: Fix data stomping during mmc recovery
stable inclusion from stable-v5.10.147 commit 9b751b4dc350a5ba836fb33518da1daac5b4a205 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I6D0W8 Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=9b751b4dc350a5ba836fb33518da1daac5b4a205 -------------------------------- commit e7afa79a upstream. The block device uses multiple queues to access emmc. There will be up to 3 requests in the hsq of the host. The current code will check whether there is a request doing recovery before entering the queue, but it will not check whether there is a request when the lock is issued. The request is in recovery mode. If there is a request in recovery, then a read and write request is initiated at this time, and the conflict between the request and the recovery request will cause the data to be trampled.
