Hi all,
These are new releases of dm-ioband and blkio-cgroup. The major
changes of these releases are:
- dm-ioband can be configured through the cgroup interface. The
bandwidth can be assigned on a per cgroup per block device basis.
- The event tracing is supported that helps in debugging and
monitoring dm-ioband.
- A document for blkio-cgroup is available at
Documentation/cgroup/blkio.txt.
This series of patches consists of two parts:
dm-ioband v1.12.1
dm-ioband is an I/O bandwidth controller implemented as a
device-mapper driver and can control bandwidth on per partition, per
user, per process, per virtual machine (such as KVM or Xen) basis.
blkio-cgruop v9
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.
The patches can be applied to both the current device-mapper development
tree and 2.6.31-rc3.
The list of the patches:
[PATCH 1/9] I/O bandwidth controller and BIO tracking
[PATCH 2/9] dm-ioband-1.12.1: All-in-one patch
[PATCH 3/9] blkio-cgroup-v9: The new page_cgroup framework
[PATCH 4/9] blkio-cgroup-v9: Refactoring io-context initialization
[PATCH 5/9] blkio-cgroup-v9: The body of blkio-cgroup
[PATCH 6/9] blkio-cgroup-v9: The document of blkio-cgroup
[PATCH 7/9] blkio-cgroup-v9: Page tracking hooks
[PATCH 8/9] blkio-cgroup-v9: Fast page tracking
[PATCH 9/9] blkio-cgroup-v9: Add a cgroup support to dm-ioband

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