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.
V3:
- avoid extra cost to blk_mq_complete_request
V2:
- export via EXPORT_SYMBOL_GPL
- minor commit log change
Ming Lei (2):
blk-mq: introduce blk_mq_complete_request_sync()
