overlayfs hooks were also posted to and discussed on lsm list, including
comments from you. Admittedly the cover patch said Overlayfs SELinux
Support but the individual patches for the hooks were "security,
overlayfs: provide copy up security hook for unioned files" and
"security,overlayfs: Provide security hook for copy up of xattrs for
overlay file".
In either case, did you request a change that was ignored?
