[PATCH v3 3/5] blk-mq: export helpers

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Omar Sandoval <osandov@xxxxxx>

blk_mq_finish_request() is required for schedulers that define their own
put_request(). blk_mq_run_hw_queue() is required for schedulers that
hold back requests to be run later.
