The foreign dirtier issue is all about identifying the memcg (or
possibly multiple bdi) that need balancing.    If the foreign dirtier
issue is not important then we can focus on identifying inodes to
writeback that will lower the current's memcg dirty usage.  I am fine
ignoring the foreign dirtier issue for now and breaking the problem
into smaller pieces.

ok.

I think this can be done with out any additional state.  Can just scan
the memcg lru to find dirty file pages and thus inodes to pass to
sync_inode(), or some other per-inode writeback routine?

I think it works, finding inodes to be cleaned by LRU scanning.

Thanks,
