Re: [PATCH] - Improve drain pages performance on large systems

Heavy swapping within a cpuset causes frequent calls to drain_all_pages().

I suspect drain_all_pages should be really made more zone aware in the
first place and only drain what is actually needed (e.g.
work off a zonelist). I was fighting with this for hwpoison too.

That said your patch looks reasonable.
