From: Steven Rostedt Date: Wed, 19 Nov 2008 04:57:14 +0000 (-0500) Subject: ftrace: make filtered functions effective on setting X-Git-Tag: v2.6.28-rc6~9^2^2~1 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=820432783190b4096499e38a4a4d7095c511913d;p=linux-2.6-omap-h63xx.git ftrace: make filtered functions effective on setting Impact: fix filter selection to apply when 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.
