DESCRIPTION bio_endio will end I/O on the whole bio. bio_endio is the preferred way to end I/O on a bio, it takes care of clearing BIO_UPTODATE on error. error is 0 on success, and and one of the established -Exxxx (-EIO, for instance) error values in case something went wrong. Noone should call bi_end_io directly on a bio unless they own it and thus know that it has an end_io function.
