NAME

6       bio_copy_data - copy contents of data buffers from one chain of bios to
7       another
8

SYNOPSIS

10       void bio_copy_data(struct bio * dst, struct bio * src);
11

ARGUMENTS

13       dst
14           destination bio list
15
16       src
17           source bio list
18

DESCRIPTION

20       If src and dst are single bios, bi_next must be NULL - otherwise,
21       treats src and dst as linked lists of bios.
22
23       Stops when it reaches the end of either src or dst - that is, copies
24       min(src->bi_size, dst->bi_size) bytes (or the equivalent for lists of
25       bios).
