Hi Barry,
Thanks for the wonderful test program.
I have also used other swap test programs as well. A lot of those
tests are harder to setup up and run.
This test is very quick and simple to run. It can test some hard to
hit corner cases for me.
I am able to reproduce the warning and the kernel
Hi Nhat,
Thanks for the self test.

Hi Nhat,
Still working my way up of your patches series.

Hi Nhat,
Very minor nitpick. This patch can fold with the later patch that uses
it. That makes the review easier, no need to cross reference different
patches. It will also make it harder to introduce API that nobody
uses.

This idea is
suggested by Yu Zhao, credit goes to him not me.
In other words, the current patch is similar to the memcg page list
pre MGLRU world. We can have a MRLRU
like per memcg zswap shrink list.

Hi Nhat,
Sorry for being late to the party. I want to take a look at your patches series.
However I wasn't able to "git am" your patches series cleanly on current
mm-stable, mm-unstable or linux tip.
$ git am
