I don't think no-fix to this is ok.

Here is a thread pool patch on your set. (and includes some more).
3 patches in following e-mails.
Any comments are welocme, but my response may be delayed.

Thank you for making up the patch, and I will take a look. Do I apply the 3 patches on top of my patchset or they comes separately?

Sorry, please ignore my last question. Looks like the patch are based on my existing per-memcg kswapd patchset. I will try to apply it.
