Hi everyone, These patchsets are the new releases of dm-ioband and bio-cgroup which are ported to 2.6.27-rc5-mm1. dm-ioband 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 block device. A job is a group of processes with the same pid or pgrp or uid or a virtual machine such as KVM or Xen. A job can also be a cgroup by applying the bio-cgroup patch. bio-cgroup Bio-cgroup is a BIO tracking mechanism, which is implemented on the cgroup memory subsystem. With the mechanism, it is able to determine which cgroup each of bio belongs to, even when the bio is one of delayed-write requests issued from a kernel thread such as pdflush. The following is a list of patches: [PATCH 1/8] dm-ioband: Patch of device-mapper driver [PATCH 2/8] dm-ioband: Documentation of design overview, installation, command reference and examples. [PATCH 3/8] bio-cgroup: Introduction [PATCH 4/8] bio-cgroup: Split the cgroup memory subsystem into two parts [PATCH 5/8] bio-cgroup: Remove a lot of "#ifdef"s [PATCH 6/8] bio-cgroup: Implement the bio-cgroup [PATCH 7/8] bio-cgroup: Add a cgroup support to dm-ioband [PATCH 8/8] bio-cgroup: Dirty page tracking Please see the following site for more information: Linux Block I/O Bandwidth Control Project http://people.valinux.co.jp/~ryov/bwctl/ Thanks, Ryo Tsuruta
