Merge tag 'for-5.16/block-2021-11-09' of git://git.kernel.dk/linux-block
Pull block fixes from Jens Axboe: - Set of fixes for the batched tag allocation (Ming, me) - add_disk() error handling fix (Luis) - Nested queue quiesce fixes (Ming) - Shared tags init error handling fix (Ye) - Misc cleanups (Jean, Ming, me) * tag 'for-5.16/block-2021-11-09' of git://git.kernel.dk/linux-block: nvme: wait until quiesce is done scsi: make sure that request queue queiesce and unquiesce balanced scsi: avoid to quiesce sdev->request_queue two times blk-mq: add one API for waiting until quiesce is done blk-mq: don't free tags if the tag_set is used by other device in queue initialztion block: fix device_add_disk() kobject_create_and_add() error handling block: ensure cached plug request matches the current queue block: move queue enter logic into blk_mq_submit_bio() block: make bio_queue_enter() fast-path available inline block: split request allocation components into helpers block: have plug stored requests hold references to the queue blk-mq: update hctx->nr_active in blk_mq_end_request_batch() blk-mq: add RQF_ELV debug entry blk-mq: only try to run plug merge if request has same queue with incoming bio block: move RQF_ELV setting into allocators dm: don't stop request queue after the dm device is suspended block: replace always false argument with 'false' block: assign correct tag before doing prefetch of request blk-mq: fix redundant check of !e expression
