[Xen-devel] [PATCH 1/8] blkio-cgroup-v11: Introduction

Hi all,

This is a new release of blkio-cgroup v11.

- The function cgroup_get_from_page() is added which determines to
  which cgroup a given page belongs. This function is introduced from
  Vivek's io-controller patch. Thanks Vivek.
- Fix a type mismatch of the refcount of io_context. The refcount has
  been changed to atomic_long_t.

This patch can be applied to 2.6.31-rc7.

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.

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