ocfs2: Add ocfs2_trace.h. (80a9a84d) · Commits · 戴 / test

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.
