This has been said by others before but: there is no reason the above
line of discussion can't happen on LKML et. al. (preferably now).
Deferring the discussion until Oct 17 guarantees that no solution would
be merged into 2.6.32. This would be quite unfortunate considering how
far Vivek's IO Controller has come. Aren't there also doubts about
whether the appropriate upstream people will be able to attend this
mini-summit?

I don't mean to defer the discussion until the mini-summit. I would
like to discuss about the above topic anytime in mailing lists and
hear opinions from the upstream people.
