From 07f4e4f790895d55f46aaf89e7437da4a585989c Mon Sep 17 00:00:00 2001 From: Frederic Weisbecker Date: Mon, 29 Sep 2008 20:27:42 +0200 Subject: [PATCH] tracing/ftrace: adapt mmiotrace to the new type of print_line Adapt mmiotrace to the new print_line type. By default, it ignores (and consumes) types it doesn't support.
