Hi everyone,
This is dm-ioband version 1.0.0 release.
Dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver, which gives specified bandwidth to each job running on the same physical device.
- Can be applied to the kernel 2.6.26-rc2-mm1. - Changes from 0.0.4 (24th April): - Performance tuning - A new bandwidth control policy is added. This policy controls bandwidth based on the number of I/O sectors instead of the number of I/O requests. I think it would be useful for some applications such as video streaming or when you want to use high-end storages. - Control read and write requests separately. So even if a write I/O queue in an elevator is full, read I/O requests won't be blocked. - More accurate bandwidth control. - Code cleanups. Remove the "LINUX_VERSION_CODE" and "inline" stuff. - Fix panic on "dmsetup suspend."

Thanks, Ryo Tsuruta
