Johannes Weiner 1f14c1ac19 mm: memcg: do not allow task about to OOM kill to bypass the limit ... Commit 4942642080 ("mm: memcg: handle non-error OOM situations more gracefully") allowed tasks that already entered a memcg OOM condition to bypass the memcg limit on subsequent allocation attempts hoping this would expedite finishing the page fault and executing the kill. David Rientjes is worried that this breaks memcg isolation guarantees and since there is no evidence that the bypass actually speeds up fault processing just change it so that these subsequent charge attempts fail outright. The notable exception being __GFP_NOFAIL charges which are required to bypass the limit regardless.
