Frederic Weisbecker f921281930 perf: Make the trace events sample period default to 1 ... Trace events are mostly used for tracing and then require not to be lost when possible. As opposite to hardware events that really require to trigger after a given sample period, trace events mostly need to trigger everytime. It is a frustrating experience to trace with perf and realize we lost a lot of events because we forgot the "-c 1" option. Then default sample_period to 1 for trace events but let the user override it.
