Greg, sorry that the mem_cgroup_dirty_info() interfaces and tracepoints are abridged since they are not used here. Obviously this patch series is not enough to keep the number of dirty pages under control. It only tries to improve page reclaim behavior given whatever dirty number. We'll need further schemes to keep dirty pages under sane levels, so that unrelated tasks do not suffer from reclaim waits when there are heavy writers in the same memcg.
