From e0a413f619ef8bc366dafc6f8221674993b8d85f Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Thu, 29 Sep 2011 21:26:16 -0400 Subject: [PATCH] tracing: Warn on output if the function tracer was found corrupted As the function tracer is very intrusive, lots of self checks are performed on the tracer and if something is found to be strange it will shut itself down keeping it from corrupting the rest of the kernel. This shutdown may still allow functions to be traced, as the tracing only stops new modifications from happening. Trying to stop the function tracer itself can cause more harm as it requires code modification. Although a WARN_ON() is executed, a user may not notice it. To help the user see that something isn't right with the tracing of the system a big warning is added to the output of the tracer that lets the user know that their data may be incomplete.
