I agree that reducing locking scope is often problematic. However,
this patch does not globally remove the io_request_lock. The purpose
of the patch is to protect request queue integrity with a per queue
lock instead of the global io_request_lock. My intent was to leave
other io_request_lock serialization intact. Any insight into whether
the patch leaves data unprotected would be appreciated.
