Subject: [PATCH V8 04/15] perf tools: change machine__findnew_thread() to set thread pid
Date: Thu, 18 Jul 2013 13:42:46 +0300	[thread overview]
Message-ID: <1374144177-24762-5-git-send-email-adrian.hunter@intel.com> (raw)
In-Reply-To: <1374144177-24762-1-git-send-email-adrian.hunter@intel.com>

Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

Signed-off-by: Adrian Hunter <adrian.hunter@intel.com>
