Message-ID: <4CDA08B6.2070002@oracle.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: ocfs2-devel@oss.oracle.com Hi all, This patch set is my first try to add trace event to ocfs2. Wengang Wang has did some work in this field about one year ago. http://oss.oracle.com/pipermail/ocfs2-devel/2009-September/005230.html But at that time we don't have ocfs2 1.6 introduced, so we delay this work until now after ocfs2 1.6 and UEK(Unbreakable Enterprise Kernel) are released. Patch 1 is actually a clean up and unrelated to trace event, but if we don't have this one, patch 2/3/4/5 won't be applied cleanly, so I'd like to include it here. Patch 2 and 3 are my attempt to remove ML_ENTRY and ML_EXIT. These 2 flags are overused and actually enabling them means disasters in our debugging. Patch 4/5 are the real patches for trace event. Please review these 2 patches. And if it is ok, I will go ahead with other files under fs/ocfs2/. Regards, Tao
