Hi all,
This is a new release of bio-cgroup which provides an IO tracking
mechanism. The patches can be applied to the kernel 2.6.30-rc1 and you
can also download them from the following site.

What's bio-cgroup all about?
This patch makes the page_cgroup framework be able to be used even if
the compile option of the cgroup memory controller is off.
So bio-cgroup can use this framework without the memory controller.

Hi,
For some days I have been looking for the bug that causes an easily
reproducible oops in the guest
when I apply my PAE support _draft_ patch (appended at the end of this mail) to
