Subject: [PATCH 0/4] blk-mq: improve dispatch lock & quiesce implementation
Date: Fri, 3 Dec 2021 21:15:30 +0800 [thread overview]
Message-ID: <20211203131534.3668411-1-ming.lei@redhat.com> (raw)
Hello,
The 1st patch replaces hctx_lock/hctx_unlock with
blk_mq_run_dispatch_ops(), so that the fast dispatch code path gets
optimized a bit.
The 2nd patch moves srcu from hctx into request queue.
The last two patches call blk_mq_run_dispatch_ops once in case of
issuing directly from list.
Ming Lei (4):
blk-mq: remove hctx_lock and hctx_unlock
blk-mq: move srcu from blk_mq_hw_ctx to request_queue
blk-mq: pass request queue to blk_mq_run_dispatch_ops
blk-mq: run dispatch lock once in case of issuing from list
