ocfs2 is network-related filesystem and need to be mounted from netmount, rather than from localmount. Adding 'ocfs2' to NET_FS_LIST will allow proper mounting and unmouning of those filesystems. While we're on the subject, couln't we check if fstab entry has _netdev in it's options, instead of keeping a list of network filesystems? Perhaps both?
