mm: memcg: do not trap chargers with full callstack on OOM
It should solve some soft lockup I observed on different machines
recently. For me myself, I only care about 3.10. :-p
commit 4942642080ea82d99ab5b65 (mm: memcg: handle non-error OOM
situations more gracefully) seems needed as a followup. Johannes
should know much better than I do.
Let me know if you need any more information or help from me.
