From 4c69e6ea415a35eb7f0fc8ee9390c8f7436492a2 Mon Sep 17 00:00:00 2001 From: Sahara Date: Mon, 15 Apr 2013 11:13:15 +0900 Subject: [PATCH] tracepoints: Prevent null probe from being added Somehow tracepoint_entry_add_probe() function allows a null probe function. And, this may lead to unexpected results since the number of probe functions in an entry can be counted by checking whether a probe is null or not in the for-loop. This patch prevents a null probe from being added. In tracepoint_entry_remove_probe() function, checking probe parameter within the for-loop is moved out for code efficiency, leaving the null probe feature which removes all probe functions in the entry.
