Subject: [PATCH 0/2] dm-ioband: I/O bandwidth controller v1.7.0:
 Introduction

Hi everyone,

This is the dm-ioband version 1.7.0 release.

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
physical device.

- Can be applied to the kernel 2.6.27-rc5-mm1.
- Changes from 1.6.0 (posted on Sep 24, 2008):
  - Fix a problem that processes issuing I/Os are permanently blocked
    when I/O requests to reclaim pages are consecutively issued.

You can apply the latest bio-cgroup patch to this dm-ioband version.
The bio-cgroup provides a BIO tracking mechanism with dm-ioband.
Please see the following site for more information:

Thanks,
Ryo Tsuruta
