From ee02a2e5c88ca2e4d6921f08d037b46d5bf82641 Mon Sep 17 00:00:00 2001 From: Steven Rostedt Date: Sat, 15 Nov 2008 16:31:41 -0500 Subject: ftrace: make filtered functions effective on setting Impact: set filtered functions at time the filter is set It can be confusing when the set_filter_functions is set (or cleared) and the functions being recorded by the dynamic tracer does not match. This patch causes the code to be updated if the function tracer is enabled and the filter is changed.
