-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.
+dnl # 4.3 API change
+dnl # Error argument dropped from bio_endio in favor of newly introduced
+dnl # bio->bi_error. This also replaces bio->bi_flags value BIO_UPTODATE.
