Konstantin Belousov abc1515601 NFSv4 client tracks opens, and the track records are only dropped when ... the vnode is inactivated. This contradicts with the nullfs caching which keeps upper vnode around, as consequence keeping the use reference to lower vnode. Add a filesystem flag to request nullfs to not cache when mounted over that filesystem, and set the flag for nfs v4 mounts.
