What: /sys/o2cb symlink

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
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
ocfs2-devel@oss.oracle.com.

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.
Who: ocfs2-devel@oss.oracle.com

What: Ability for non root users to shm_get hugetlb pages based on mlock
resource limits
When: 2.6.31
