From ad915c432eccb482427c1bbd77c74e6f7bfe60b3 Mon Sep 17 00:00:00 2001 From: David Rientjes Date: Mon, 9 Aug 2010 17:18:53 -0700 Subject: [PATCH] oom: enable oom tasklist dump by default The oom killer tasklist dump, enabled with the oom_dump_tasks sysctl, is very helpful information in diagnosing why a user's task has been killed. It emits useful information such as each eligible thread's memory usage that can determine why the system is oom, so it should be enabled by default.
