Subject: [PATCH 1/7] blkio-cgroup-v10: Introduction
Hi all,
This is a new release of blkio-cgroup v10. This release reduces
IO tracking overhead and fixes an issue that could cause a deadlock
since lock_page_cgroup() is no longer used.
Thank you KAMEZAWA-san for your suggestions and pointing out the issue.
This patch can be applied to 2.6.31-rc3-mmotm0716 and 2.6.31-rc4.
The list of the patches:
[PATCH 1/7] blkio-cgroup-v10: Introduction
[PATCH 2/7] blkio-cgroup-v10: The new page_cgroup framework
[PATCH 3/7] blkio-cgroup-v10: Refactoring io-context initialization
[PATCH 4/7] blkio-cgroup-v10: The body of blkio-cgroup
[PATCH 5/7] blkio-cgroup-v10: The document of blkio-cgroup
[PATCH 6/7] blkio-cgroup-v10: Page tracking hooks
[PATCH 7/7] blkio-cgroup-v10: Add a cgroup support to dm-ioband
About blkio-cgroup:
blkio-cgroup is a block I/O tracking mechanism implemented on the
cgroup memory subsystem. Using this feature the owners of any type of
I/O can be determined. This allows dm-ioband to control block I/O
bandwidth even when it is accepting delayed write requests. dm-ioband
can find the cgroup of each request. It is also for possible that
others working on I/O bandwidth throttling to use this functionality
to control asynchronous I/O with a little enhancement.
Please visit our website, the patches and more information are available.

I'd like to get some feedbacks from the list. Any comments are
appreciated.
Thanks,
Ryo Tsuruta
