Shouldn't this and the checks for no_llseek simply be merged into patch
2?

No function change, but in general checking for the error condition
in the branch tends to be more readable.  i.e.:

	if (!(file->f_mode & FMODE_LSEEK) || !file->f_op->llseek)
		return -ESPIPE;
	return file->f_op->llseek(file, offset, whence);
