Hi Ryo,

The page_cgroup seems to be stable in the latest kernel.
I'd like to know whether you have a plan or schedule to release
a new version of bio-cgroup against latest kernel.

Thanks a lot.

I have a plan on doing this.

I thought I would start to implement it once the implementation of
memory cgroup got almost done. If you say the code of page_cgroup is
fixed, I'll start it from now on. I guess it'll be done in two weeks.

code to page_cgroup itself will not be changed. (I hope)
possible change will be
  - new flags
  - support to SwapCache
  - swap_cgroup support (will be done independenly from page_cgroup.)

API of
   lookup_page_cgroup()
   lock_page_cgroup()
   PCG_USED bit

will not change, I think.

Thanks,

I think you should not wait for stabilization, rather build on mmotm (-mm). Use
it and complain if it changes too often or becomes unusable for you.
