Sure. As I said, I don't think that the procfs part is a blocker - if YiFei doesn't want to implement it now, I don't think it's necessary. (But it would make it possible to write more precise tests.) By the way: Please don't top-post on mailing lists - instead, quote specific parts of a message and reply below those quotes. Also, don't send HTML mail to kernel mailing lists, because they will reject it.
