I'm sorry for lack of documentation.
BTW, when you adds documentation on this pagein/pageout, please make it clear

1. pagein means a new page is newly acconted to this cgrop, doesn't means
   a page is read from disk.
2. pageout means a page is dropped from this cgroup, doesn't means a page
   is written into disk.

So, pagein/pageout is a bit ambiguous. I'm happy if you find better names.


Thanks,
