Hey Ming,

So is nvme-tcp also affected here? The only point where I see nvme-tcp
can be affected is when initializing a bvec iter using bio_segments() as
everywhere else we use iters which should transparently work..

I see that loop was converted, does it mean that nvme-tcp needs to
call something like?
--
bio_for_each_mp_bvec(bv, bio, iter)
nr_bvecs++;
--
