Historically it has been a mix of the NFS and SELinux folks that have worked on it and contributed patches, with code sprinkled between the two subsystems (and possibly elsewhere too). I suspect a better question would be: who should you work with to discuss issues the labeled NFS code? I don't want to assume too much, but I think you know the answer to that one already ;) -- paul moore www.paul-moore.com
