Hi Steve-
This short series addresses a couple of problems found with
umount.nfs. See RH bugzilla 492598.
After this series is applied, umount.nfs will send UMNT requests from
a privileged source port. This appears to match the behavior of
umount.nfs before nfs-utils 1.1.5, and is required when the "secure"
export option is used on the server.
A minor problem with the value returned by nfs_mount_protocol() is
also addressed. This might affect umount.nfs and NFSv2/v3
version/protocol fallback by sending MNT and UMNT requests using
the wrong transport protocol.
