From 80a9a84da381087ed89f5fdfc40a513cf9768ac4 Mon Sep 17 00:00:00 2001 From: Wengang Wang Date: Mon, 21 Feb 2011 11:13:14 +0800 Subject: [PATCH] ocfs2: Add ocfs2_trace.h. About one year ago, Wengang Wang tried some first steps to add tracepoints to ocfs2. Hiss original patch is here: http://oss.oracle.com/pipermail/ocfs2-devel/2009-November/005512.html But as Steven Rostedt indicated in his article http://lwn.net/Articles/383362/, we'd better have our trace files resides in fs/ocfs2, so I rewrited the patch using the method Steven mentioned in that article.
