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. Linux Block I/O Bandwidth Control Project http://sourceforge.net/apps/trac/ioband/ I'd like to get some feedbacks from the list. Any comments are appreciated.
