commit 281ca299724f24e7b19c1eca04bba03410e2a306
Author: Jeff Layton <jlaton@redhat.com>
Date:   Wed May 7 10:35:30 2008 -0400

    The bg option is essentially ignored with nfs4 currently. nfs4mount()
    will never exit with EX_BG, so the mount will never be backgrounded.
    Fix it so that when bg is specified that we error out with EX_BG as
    soon as possible after the first failed mount attempt.
