BIO_COPY_DATA(9)                          The Linux VFS                          BIO_COPY_DATA(9)



NAME
       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).
