Since you like posting links:

If you want to resurrect your patches, go ahead. I'll pull them into my
list. Probably should rename seq_overflow() to seq_is_full(), which
makes it sound less of an error.

And as Al noted, only fix what's there (just the places that check the
return values). Don't add anything else.
