[PATCH 03/10] perf session: Dont queue events w/o timestamps

From: Arnaldo Carvalho de Melo
Date: Thu Dec 09 2010 - 13:14:28 EST


From: Thomas Gleixner <tglx@xxxxxxxxxxxxx>

If the event has no timestamp assigned then the parse code sets it to
~0ULL which causes the ordering code to enqueue it at the end.

Process it right away.
