dnl # 2.6.24 API change
dnl # Size argument dropped from bio_endio and bi_end_io, because the
dnl # bi_end_io is only called once now when the request is complete.
dnl # There is no longer any need for a size argument. This also means
dnl # that partial IO's are no longer possibe and the end_io callback
dnl # should not check bi->bi_size. Finally, the return type was updated
dnl # to void.
