bio_copy_data (9) Linux Manual Page
bio_copy_data – copy contents of data buffers from one chain of bios to another
Synopsis
void bio_copy_data(struct bio *dst, struct bio *src);Arguments
dst
-
- destination bio list
src
- source bio list
Description
If src and dst are single bios, bi_next must be NULL – otherwise, treats src and dst as linked lists of bios.
Stops when it reaches the end of either src or dst – that is, copies min(src->bi_size, dst->bi_size) bytes (or the equivalent for lists of bios).
