DESCRIPTION

19       The caller won't have a bi_end_io called when bio completes - instead,
20       parent's bi_end_io won't be called until both parent and bio have
21       completed; the chained bio will also be freed when it completes.
22
23       The caller must not set bi_private or bi_end_io in bio.
