Subject: [PATCH V2 0/5] blk-mq: quiesce improvement
Date: Tue, 30 Nov 2021 15:37:47 +0800 [thread overview]
Message-ID: <20211130073752.3005936-1-ming.lei@redhat.com> (raw)
Hi Guys,
The 1st patch removes hctx_lock and hctx_unlock, and optimize dispatch
code path a bit.
The 2nd patch moves srcu from blk_mq_hw_ctx to request_queue.
The other patches add one new helper for supporting quiesce in parallel.
V2:
- add patch of 'remove hctx_lock and hctx_unlock'
- replace ->alloc_srcu with queue flag, as suggested by Sagi
Ming Lei (5):
blk-mq: remove hctx_lock and hctx_unlock
blk-mq: move srcu from blk_mq_hw_ctx to request_queue
blk-mq: add helper of blk_mq_shared_quiesce_wait()
nvme: quiesce namespace queue in parallel
scsi: use blk-mq quiesce APIs to implement scsi_host_block
