    tracing: add protection around open use of current_tracer · d8e83d26

    Impact: fix to possible race conditions
    There's some uses of current_tracer that is not protected by the
    trace_types_lock. There is a small chance that a sysadmin changes
    the tracer while the current_tracer is being referenced.
    If the race is hit, it is unlikely to cause any harm since the
    tracers are constant and are not freed. But some strang side
    effects may occur.
