3.8-stable review patch. If anyone has any objections, please let me know.
------------------ From: Jan Kiszka <[email protected]> commit 5000c418840b309251c5887f0b56503aae30f84c upstream. If we reenable ftrace via syctl, we currently set ftrace_trace_function based on the previous simplistic algorithm. This is inconsistent with what update_ftrace_function does. So better call that helper instead.
