If dropping my patch (1f4c6a1cf274 ("mm, memcg: inline
mem_cgroup_{charge/uncharge} to improve disabled memcg config")) helps
in resolving this, feel free to do that and I'll redo it after folios
are merged.

That commit is now

  2c8d8f97ae22 ("mm, memcg: inline mem_cgroup_{charge/uncharge} to improve disabled memcg config")

and is merged in Linus' tree already.
