Hi Can, Since your patch restores a call that was removed earlier, please consider adding a Fixes: tag to your patch. Please also have a look at https://git.kernel.org/pub/scm/linux/kernel/git/mkp/scsi.git/log/?h=5.6/scsi-queue. As one can see my patches that introduce blk_cleanup_queue() and blk_mq_free_tag_set() calls have already been queued on Martin's 5.6/scsi-queue branch. Bart.
