This patchset is intended to transfer the LRU pages to the object cgroup

Thanks. I'll add this to mm.git for testing. A patchset of this
magnitude at -rc5 is a little ambitious, but Linus is giving us an rc8
so let's see.

I'll suppress the usual added-to-mm email spray.

Hi Andrew,

The issue reported by syzbot needs to be addressed. If you want to test
this patchset, would you like me to provide a fix patch, or would you
prefer me to update to v4?

A fix would be preferred if that's reasonable - it's a lot of patches
be resending!

OK, I'll send the fix ASAP.
