[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.
