| submit_bio | submit_bio - submit a bio to the block device layer for I/O*@bio: The &struct bio which describes the I/O* submit_bio() is very similar in purpose to generic_make_request(), and* uses that function to do most of the work. Both are fairly rough |
| blk_rq_map_sg | map a request to scatterlist, return number of sg entries setup. Caller* must make sure sg can hold rq->nr_phys_segments entries |
| bfq_limit_depth | Async I/O can easily starve sync I/O (both sync reads and sync* writes), by consuming all tags |
