From: Steven Rostedt Date: Tue, 26 Apr 2011 20:11:03 +0000 (-0400) Subject: ftrace: Move record update for normal and modules into a separate function X-Git-Tag: upstream/snapshot3+hdmi~10413^2~16^2~2 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=996e87be7f537fb34638875dd37083166c733425;p=platform%2Fadaptation%2Frenesas_rcar%2Frenesas_kernel.git ftrace: Move record update for normal and modules into a separate function The updating of a function record is moved to a single function. This will allow us to add specific changes in one location for both modules and kernel functions. Later patches will determine if the function record itself needs to be updated (which enables the mcount caller), or just the ftrace_ops needs the update.
