Ah, nevermind, I can reproduce the issue easily. After some more poking I now think the bisect would lead to the OOM rework, but it would be a red herring. Seems like this is an interaction between bind mempolicy and cpuset and I see several potential bugs in that area. Which also means there's a non-null nodemask and thus the code in the commit I originally suspected (replacing NULL nodemask with cpuset's mems_allowed) doesn't trigger at all here.
