Minor nit: the reverse xmas tree order is based on the full line len,
should be:
	int err = 0;
	u32 len, i;

Minor nit: 'oom' is used only in the above to lines. You could drop
such variable and just:
	return err != -ENOMEM;

Please _do not_ repost just for the above, but please include such
changes if you should repost for other reasons.

Also try to include a detailed changelog in each patch after the tag
area and a '---' separator, it will simplify the review process.

Thanks,
