OK, I'll do a smaller IO-less balance_dirty_pages() patchset (it's
good to know which part is the most relevant one, which is not always
obvious by my limited field experiences), which will further reduce
the possible risk of unexpected regressions.

Currently the -mm tree includes Greg's patchset "memcg: per cgroup
dirty page accounting". I'm going to rebase my patches onto it,
however I'd like to first make sure if Greg's patches are going to be
pushed in the next merge window. I personally have no problem with
that.  Andrew?

Thanks,
Fengguang
