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

...d, or tid, to cgroups? -- what ID is OK to write to "tasks" file and what we can expect as a result? Tsuruta-san, how about your bio-cgroup's tracking concerning this? If we want to use your tracking functions for each threads seperately, there seems to be a problem. ===cf. mm_get_bio_cgroup()=================== owner mm_struct ----> task_struct ----> bio_cgroup ============================================= In my understanding, the mm_struct of a thread is same as its parent's. So, even if we attach the TIDs of some threads to different cgroups the tracking always...

Hi, If you are not already tired of so many io controller implementations, here is another one. This is a very eary very crude implementation to get early feedback to see if this approach makes any sense or not. This controller is a proportional weight IO controller primarily based on/inspired by dm-ioband. One of the things I personally found little odd about dm-ioband was need of a dm-ioband

and nice. My concern is "bio_cgroup_id". It's provided only for bio_cgroup. In this summer, I tried to add swap_cgroup_id only for mem+swap controller but commenters said "please provide "id and lookup" in cgroup layer, it should be useful." And I agree them. (and postponed it ;) Could you try "id&q...

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
