+Description:
+ For latency improvements, some storage devices could
+ provide a mechanism for servicing demand paging and
+ swapin requests in a high priority manner. Setting
+ these flags to 1 would get the requests marked with
+ REQ_RW_DMPG or REQ_RW_SWAPIN to be moved to the front
+ of elevator queue.
