IMO, the only one left is raid(1/5/10) which can be dealt with by the
"NO_MP" flag. This point can be observed by result from runnig 'git grep':
$git grep -n -E "bi_vcnt|bi_io_vec" ./
Also this patchset addes comment in cases of direct access to bvec table,
and the cases have been minimized too, and most of them are single
bvec based.
