From db271cf03f5fe39feab8e1b1818c0880c7290c5c Mon Sep 17 00:00:00 2001 From: Richard Weinberger <richard@nod.at> Date: Tue, 24 May 2011 17:13:04 -0700 Subject: [PATCH] um: fix crash while os_dump_core() os_dump_core() emits SIGTERM to terminate all UML processes. Kernel threads have to exit on SIGTERM instead of calling last_ditch_exit(). Multiple calls to last_ditch_exit() can cause a crash.
