From: James Lentini Date: Mon, 24 Sep 2007 17:32:49 -0400 (EDT) [NFS] [PATCH] NFS: initialize default port in kernel mount client If no mount server port number is specified, the previous change to the kernel mount client inadvertently allows the NFS server's port number to be the used as the mount server's port number. If the user specifies an NFS server port (-o port=x), the mount will fail. The fix below sets the mount server's port to 0 if no mount server port is specified by the user.
