[PATCH 5.15 024/244] tracing: Have filter accept "common_cpu" to be consistent

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Steven Rostedt (Google) <rostedt@xxxxxxxxxxx>

commit b2380577d4fe1c0ef3fa50417f1e441c016e4cbe upstream.

Make filtering consistent with histograms. As "cpu" can be a field of an
event, allow for "common_cpu" to keep it from being confused with the
"cpu" field of the event.
