3.6.11.3 stable review patch. If anyone has any objections, please let me know. ------------------ From: Jan Kiszka [ Upstream commit 5000c418840b309251c5887f0b56503aae30f84c ] 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.
