From ee386de77419f9fedf206d84c4d4b2de0ead5bcb Mon Sep 17 00:00:00 2001 From: Paul Mundt Date: Mon, 8 Sep 2008 18:12:33 +0900 Subject: [PATCH] sh: kprobes: Default to NOTIFY_DONE for unhandled debug traps. Presently this is doing a force_sig() SIGTRAP, which is already taken care of in the generic code if no one asserts NOTIFY_STOP. Switch the default return to NOTIFY_DONE in the case of unhandled traps, so that the same trap may pass through to other users on the same die chain.
