2480945cd44b50ba8b1646544eec2db21f064f12 dm bufio: submit writes outside lock
This patch changes dm-bufio so that it submits write I/Os outside of the
lock. If the number of submitted buffers is greater than the number of
requests on the target queue, submit_bio blocks. We want to block outside
of the lock to improve latency of other threads that may need the lock.
