3.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Namhyung Kim <namhyung.kim@xxxxxxx> commit 9f50afccfdc15d95d7331acddcb0f7703df089ae upstream. The ftrace_graph_count can be decreased with a "!" pattern, so that the enabled flag should be updated too.
