Thanks a lot for your clarifications for my questions,I'll try your
provided tools later.

For the second version(26patches) patch set you've provided, i did not
succeed to apply on your recommended kernel(Mark's linux-next branch),
but only get it done with a success on linus's mainline-2.6.27 kernel.
so it may make a little bit difference with your working environment,
will it make any hurt for quota testing?

Tristan.
