Disabling latency tracing does not seem to work. To demonstrate:

echo 0 > /proc/sys/kernel/preempt_max_latency
echo 0 > /proc/sys/kernel/trace_enabled
modprobe foo-module (will reliably cause a ~3-600 usec latency in resolve_symbol)
check /proc/latency_trace, or dmesg, it will be the modprobe latency.
cat /proc/sys/kernel/trace_enabled, it is still 0

This definitely worked at one point. Not sure when it broke.
