Going for as small as possible patchsets is a pretty good idea. Just
getting the I/O less balance_dirty_pages on it's own would be a really
good start, as that's one of the really criticial pieces of
infrastructure that a lot of people are waiting for. Getting it into
linux-mm/linux-next ASAP so that it gets a lot of testing would be
highly useful.
