ocfs2: Move /sys/o2cb to /sys/fs/o2cb
/sys/fs is where we really want file system specific sysfs objects. Ocfs2-tools has been updated to look in /sys/fs/o2cb. We can maintain backwards compatibility with old ocfs2-tools by using a sysfs symlink. After some time (2 years), the symlink can be safely removed. This patch also adds documentation to make it easier for people to figure out what /sys/fs/o2cb is used for. Signed-off-by: Mark Fasheh <mfasheh@suse.com>
