From 96de37b62ca525cd77d2e85aea1472846ee31c4d Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Sat, 7 Jan 2012 17:26:49 -0500 Subject: [PATCH] tracing: Fix compile error when static ftrace is enabled The stack tracer uses the call ftrace_set_early_filter() function to allow the stack tracer to pick its own functions on boot. But this function is not defined if dynamic ftrace is not set. This causes a compiler error when stack tracer is enabled and dynamic ftrace is not.
