I'd like to sort out topics before going. Please fix if I don't catch enough.

mentiont to 1. later...

Main topics on 2. Memcg Dirty Limit and writeback ....is

 a) How to implement per-memcg dirty inode finding method (list) and
   how flusher threads handle memcg.

I have some very rough code implementing the ideas discussed in
http://thread.gmane.org/gmane.linux.kernel.mm/59707
Unfortunately, I do not yet have good patches, but maybe an RFC series
soon.  I can provide update on the direction I am thinking.

 b) Hot to interact with IO-Less dirty page reclaim.
   IIUC, if memcg doesn't handle this correctly, OOM happens.

The last posted memcg dirty writeback patches were based on -mm at the
time, which did not have IO-less balance_dirty_pages.  I have an
approach which I _think_ will be compatible with IO-less
balance_dirty_pages(), but I need to talk with some writeback guys to
confirm.  Seeing the Writeback talk Mon 9:30am should be very useful
for me.

 Greg, do we need to have a shared session with I/O guys ?
 If needed, current schedule is O.K. ?

We can contact any interested writeback guys to see if they want to
attend memcg-writeback discussion.  We might be able to defer this
detail until Mon morning.

  Yes, I plan to take part in this discussion. If this would be joint
session with fs people (which kind of makes sense) it's simpler for
me but I can surely handle if it isn't :).
