Subject: [patch 2/9] perf: session: Dont queue events w/o timestamps
Date: Tue, 07 Dec 2010 12:48:44 -0000	[thread overview]
Message-ID: <20101207124550.528788441@linutronix.de> (raw)
In-Reply-To: <20101207124527.868085529@linutronix.de>

[-- Attachment #1: perf-session-do-not-queue-events-w-o-timestamps.patch --]
[-- Type: text/plain, Size: 805 bytes --]

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.
