Subject: [PATCH 9/9] perf, tools, record: Always allow to overide default period v2
Date: Thu, 15 May 2014 15:03:12 -0700	[thread overview]
Message-ID: <1400191392-11569-10-git-send-email-andi@firstfloor.org> (raw)
In-Reply-To: <1400191392-11569-1-git-send-email-andi@firstfloor.org>

From: Andi Kleen <ak@linux.intel.com>

Fix the logic to allow overriding event default periods with -c or -F
on the command line.  I'm not sure I understand this if() fully, but
this change makes all cases I tested work (tracepoint with default, default,
,-c, -F)

This fixed specifying -c / -F with json event list events,
which have a default period. It should do the same
for trace point events.

v2: Simplify, just change || to &&
