 I've committed a fix to autofs to use genfs_pathconf().
 Unlike FreeBSD, we fall back to return EOPNOSUPP if a filesystem
 hasn't implemented a method. FreeBSD has individual defaults for
 each method (mostly the 'generic' implementations) and the
 default for vop_pathconf is to return EINVAL unconditionally.
 N.B. mfs calls genfs_badop, i.e. triggers a panic. This should probably
 be changed.
