Subject: [PATCH V2 0/2] blk-mq/nvme: cancel request synchronously
Date: Wed, 27 Mar 2019 16:51:12 +0800 [thread overview]
Message-ID: <20190327085114.12111-1-ming.lei@redhat.com> (raw)
Hi,
This patchset introduces blk_mq_complete_request_sync() for canceling
request synchronously in error handler context, then one race between
completing request remotely and destroying contoller/queues can be fixed.
V2:
- export via EXPORT_SYMBOL_GPL
- minor commit log change
Ming Lei (2):
blk-mq: introduce blk_mq_complete_request_sync()
nvme: cancel request synchronously
