Summary
block: fix uaf for flush rq while iterating tags
Details

In the Linux kernel, the following vulnerability has been resolved:

block: fix uaf for flush rq while iterating tags

blkmqclearflushrqmapping() is not called during scsi probe, by checking blkqueueinitdone(). However, QUEUEFLAGINITDONE is cleared in delgendisk by commit aec89dc5d421 ("block: keep qusagecounter in atomic mode after delgendisk"), hence for disk like scsi, following blkmqdestroyqueue() will not clear flush rq from tags->rqs[] as well, cause following uaf that is found by our syzkaller for v6.6:
