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.
