From 0d673a5a4775d3dc565b6668ed75fd2db2ede624 Mon Sep 17 00:00:00 2001 From: Nick Piggin Date: Sun, 27 Aug 2006 01:23:54 -0700 Subject: [PATCH] [PATCH] cpuset: oom panic fix cpuset_excl_nodes_overlap always returns 0 if current is exiting. This caused customer's systems to panic in the OOM killer when processes were having trouble getting memory for the final put_user in mm_release. Even though there were lots of processes to kill. Change to returning 1 in this case. This achieves parity with !CONFIG_CPUSETS case, and was observed to fix the problem.
