From: Steven Rostedt Date: Wed, 13 Jul 2011 19:08:31 +0000 (-0400) Subject: ftrace: Update filter when tracing enabled in set_ftrace_filter() X-Git-Tag: v3.1-rc1~299^2~10^2~16 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=072126f4529196f71a97960248bca54fd4554c2d;p=platform%2Fupstream%2Fkernel-adaptation-pc.git ftrace: Update filter when tracing enabled in set_ftrace_filter() Currently, if set_ftrace_filter() is called when the ftrace_ops is active, the function filters will not be updated. They will only be updated when tracing is disabled and re-enabled. Update the functions immediately during set_ftrace_filter().
