+Description:    This is a symlink: /sys/o2cb to /sys/fs/o2cb. The symlink is
+                removed when new versions of ocfs2-tools which know to look
                 in /sys/fs/o2cb are sufficiently prevalent. Don't code new
                 software to look here, it should try /sys/fs/o2cb instead.
-                See Documentation/ABI/stable/o2cb for more information on usage.
 Users:          ocfs2-tools. It's sufficient to mail proposed changes to

-What:   /sys/o2cb symlink
-When:   January 2010
-Why:    /sys/fs/o2cb is the proper location for this information - /sys/o2cb
-        exists as a symlink for backwards compatibility for old versions of
-        ocfs2-tools. 2 years should be sufficient time to phase in new versions
-        which know to look in /sys/fs/o2cb.
