These patchsets are the new releases of dm-ioband and bio-cgroup which
are ported to 2.6.27-rc5-mm1.
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 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
