BIO_ADVANCE(9)                            The Linux VFS                            BIO_ADVANCE(9)



NAME
       bio_advance - increment/complete a bio by some number of bytes

SYNOPSIS
       void bio_advance(struct bio * bio, unsigned bytes);

ARGUMENTS
       bio
           bio to advance

       bytes
           number of bytes to complete

DESCRIPTION
       This updates bi_sector, bi_size and bi_idx; if the number of bytes to complete doesn't
       align with a bvec boundary, then bv_len and bv_offset will be updated on the last bvec as
       well.

       bio will then represent the remaining, uncompleted portion of the io.
