Hi Martin, Since a device, target or host reference may be held when scsi_remove_host() or scsi_remove_target() is called and since te patch series "Call blk_mq_free_tag_set() earlier" makes these functions wait until all references are gone, that patch series may trigger a deadlock. Hence this request to revert the patch series "Call blk_mq_free_tag_set() earlier". Thanks, Bart.
