From: Chad Talbott on
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

This has the side effect of fixing the "root cgroup shows no stats"
problem that Ricky mentioned.



Chad Talbott (4):
blkio_group key change: void * -> request_queue *
Adds an RCU-protected pointer to request_queue that makes it easy to
io-controller: Add a new interface "weight_device" for IO-Controller
Use disk-names to set blkio.weight_device policy
