The patch series does: - Move the hash backmerging into the elevator core. - Move the rbtree handling into the elevator core. - Abstract the FIFO handling into the elevator core. - Kill the io scheduler private requests, that require allocation/free for each request passed through the system. The result is a faster elevator core (and faster IO schedulers), with a nice net reduction of kernel text and code as well. If you have time, please give this patch series a test spin just to verify that everything still works for you.
