This stack (which includes Gui's patch for per-device weights), changes the various blkio.* stats to use the disks' names (sda, sdb, etc.) rather than major:minor pairs when printing statistics. Additionally setting a per-device policy can be done via the disk's name.
This has the side effect of fixing the "root cgroup shows no stats" problem that Ricky mentioned.
