Re: [RFC][PATCH v2 5/7] taskstats: Improve cumulative CPU timeaccounting

Hi Michael,

I can't read this discussion today, will try to do tomorrow and reply.
Just one note,

Something like this (if possible).

But my main concern is parallel hierarchy itself. So, if you ask me,
I'd prefer to see a separate patch which only adds acct_parent/etc
and implements this reparenting, even without cdata_acct accounting.

Again, if you think this is possible. I understand that it is not
easy to maintain this series,

Oleg.
