NFS: mount option parser chokes on proto=

chucklever · Trond Myklebust · commit fdb66ff4ace3 · 2007-09-01T10:14:38.000-04:00
The new text-based NFS mount option parsing logic doesn't recognize any
valid transport protocols due to a silly mistake in the protocol token
matching logic.  This prevents basic mount requests such as:

   mount.nfs server:/export /mnt -o proto=tcp

from working with the new text-based NFS mount API.
