    Subject[37/38] ftrace: Fix warning when CONFIG_FUNCTION_TRACER is not defined
    3.0-stable review patch.  If anyone has any objections, please let us know.

    ------------------

    From: Steven Rostedt <srostedt@redhat.com>

    commit 04da85b86188f224cc9b391b5bdd92a3ba20ffcf upstream.

    The struct ftrace_hash was declared within CONFIG_FUNCTION_TRACER
    but was referenced outside of it.
