Subject: [PATCH 2/4] tools lib traceevent: Use USECS_PER_SEC instead of hardcoded number
Date: Tue, 09 Feb 2016 15:40:15 -0500	[thread overview]
Message-ID: <20160209204237.006667394@goodmis.org> (raw)
In-Reply-To: 20160209204013.951400594@goodmis.org

[-- Attachment #1: 0002-tools-lib-traceevent-Use-USECS_PER_SEC-instead-of-ha.patch --]
[-- Type: text/plain, Size: 1314 bytes --]

From: "Steven Rostedt (Red Hat)" <rostedt@goodmis.org>

Instead of using 1000000, define a USECS_PER_SEC macro and use that instead.
