Hi,
This is a continuation of the patches posted yesterday, I continued to build on them. 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. Thanks!
