I cloned the repo and it looks like everything was present, three recent patches in all. Built and ran my tests without any kernel issue. The tests I run are limited in scope because they essentially use opendir(3) and check mtab or /proc/mounts for mount and fs type. Although I do plenty of NFS mount and umount I don't have anything that tests NFS automounts. Ian
