The major changes of these releases are: - dm-ioband can be configured through the cgroup interface. The bandwidth can be assigned on a per cgroup per block device basis. - The event tracing is supported that helps in debugging and monitoring dm-ioband. - A document for blkio-cgroup is available at Documentation/cgroup/blkio.txt. This series of patches consists of two parts: dm-ioband v1.12.1 dm-ioband is an I/O bandwidth controller implemented as a device-mapper driver and can control bandwidth on per partition, per user, per process, per virtual machine (such as KVM or Xen) basis. blkio-cgruop v9 blkio-cgroup is a block I/O tracking mechanism implemented on the cgroup memory subsystem. Using this feature the owners of any type of I/O can be determined. This allows dm-ioband to control block I/O bandwidth even when it is accepting delayed write requests. dm-ioband can find the cgroup of each request. It is also for possible that others working on I/O bandwidth throttling to use this functionality to control asynchronous I/O with a little enhancement. The patches can be applied to both the current device-mapper development tree and 2.6.31-rc3.
