bio_chain - chain bio completions

void bio_chain(struct bio * bio, struct bio * parent);
ARGUMENTS¶
struct bio * bio
the target bio

DESCRIPTION¶
The caller won't have a bi_end_io called when bio completes - instead, parent's bi_end_io won't be called until both parent and bio have completed; the chained bio will also be freed when it completes.
