[for-linus][PATCH 4/6] tracing/timerlat: Notify new max thread latency

[Steven Rostedt]

From: Daniel Bristot de Oliveira <bristot@xxxxxxxxxx>

timerlat is not reporting a new tracing_max_latency for the thread
latency. The reason is that it is not calling notify_new_max_latency()
function after the new thread latency is sampled.

Call notify_new_max_latency() after computing the thread latency.
