description:
Pull a fix from ffs_vfsops.c rev 1.248:
> Fix bug introduced in revision 1.174(*) where a NULL fspec with an MNT_UPDATE
> command would always return EINVAL. This broke fsck on root, where fsck'ing
> a dirty root would always return an error causing rc to resort in a reboot.
(*) This is "Apply the NFS exports list rototill patch" change
    in ext2fs_vfsops.c rev 1.91.
