ARGUMENTS

12       bio
13           bio to advance

DESCRIPTION

19       This updates bi_sector, bi_size and bi_idx; if the number of bytes to
20       complete doesn't align with a bvec boundary, then bv_len and bv_offset
21       will be updated on the last bvec as well.
22
23       bio will then represent the remaining, uncompleted portion of the io.
