I dropped the patch and fixed up the fallout. The patch wasn't true anyway. "There is no check at all for a failure to allocate the root inode in autofs_fill_super(), handle it." In fact, d_make_root(NULL) will just return NULL and autofs_fill_super() handles that appropriately. However let's note that when autofs_get_inode() or d_make_root() fail, autofs_fill_super() will return -EINVAL. Should have been -ENOMEM, I guess?
