[PATCH 2/2] oslat: Add trace maker prior starting main thread

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

 



After a long tracing session it's sometimes hard to find the moment
oslat started. So leave a message in the trace buffer just before the
main thread starts.
