Hi,

After this commit I can't mount from a host with the following exports:

# cat /etc/exports
/export -ro
/export/obj -maproot=root
V4: /export

# cat /etc/fstab
...
/usr/obj  /export/obj  nullfs  rw  0  0

# mount -t nfs -oro,nfsv4 vm4:/obj /mnt
mount_nfs: nmount: /mnt: Permission denied


Adding debug prints:
nam = 0xfffff80002c10700
saddr->sa_family = 28
rnh = 0

Before the commit, rnh == NULL would continue to MNT_DEFEXPORTED check.


Thanks,
Guy
