-Description: This is a symlink: /sys/o2cb to /sys/fs/o2cb. The symlink will
- be 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.

-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.
