Ok, bad news - I've been hit by kswapd0 loop again -
my kernel git commit cc19528bd3084c3c2d870b31a3578da8c69952f3 again
shown kswapd0 for couple minutes on CPU.
It seemed to go instantly away when I've drop caches
(echo 3 >/proc/sys/vm/drop_cache)
(After that I've had over 1G free memory)
Any chance you could retry with this patch on top?

Ok, I'm running now b69f0859dc8e633c5d8c06845811588fe17e68b3 (-rc8)
with your patch. I'll be able to give some feedback after couple
days (if I keep my machine running without reboot - since before
So to just give some positive info -
with 2 1/2 day uptime, several suspend/resumes, ff at 1.4GB
I still have just 29 seconds for kswapd0 process.
So the patch above might have helped - but I'll look for a few more days.
