Hi all, With this series of patches, you can determine the owners of any type of I/Os. I ported the previous version to linux-2.6.26-rc2-mm1. This makes dm-ioband -- I/O bandwidth controller -- be able to control the Block I/O bandwidths even when it accepts delayed write requests. Dm-ioband can find the owner cgroup of each request. It is also possible that OpenVz team and NEC Uchida-san team

This patchset expands traditional CFQ scheduler in order to support cgroups, and improves old version. Improvements are as following. * Modularizing our new CFQ scheduler. The expanded CFQ scheduler is registered/unregistered as new I/O elevator scheduler called "cfq-cgroups". By this, the traditional CFQ scheduler, which does not handle cgroups, and our new CFQ

Hi everyone, Here are new releases of bio-cgroup. Changes from the previous version are as follows: - Accurate dirty-page tracking Support migrating pages between bio-cgroups with minimum overhead, but I think such a situation is quite rare. - Fix a bug of swapcache page handling Sometimes, "bad page state" is occurred since the memory controller has temporarily changed the

Hi everyone, This series of patches of dm-ioband now includes "The bio tracking mechanism," which has been posted individually to this mailing list. This makes it easy for anybody to control the I/O bandwidth even when the I/O is one of delayed-write requests. Have fun! This series of patches consists of two parts: 1. dm-ioband Dm-ioband is an I/O bandwidth controller implemented
