Eh?  Just have
		host_err = mutex_lock_killable(....);
		if (host_err)
			break;
		de = ...
                while (size > 0) {
			offset = de->offset;
			if (func(cdp, de->name, de->namlen, de->offset,
				 de->ino, de->d_type))
				break;
			if (cdp->err != nfs_ok)
				break;
			...
			size -= reclen;
			de = ...
		}
		mutex_unlock(....);
		if (size > 0) /* we'd an error */
			break;
		offset = vfs_llseek(....);
	}
	free_page(....);
and to hell with all goto in there...
