Subject: [Patch -tip 3/3] Tracing/ftrace: Don't consume entries unhandled by mmiotrace
Date: Thu, 25 Sep 2008 13:28:56 +0100	[thread overview]
Message-ID: <48DB8408.7080408@gmail.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 175 bytes --]

When mmiotrace can't handle an entry output, it returns 1.
It should return 0 to relay on other output functions.
