Re: [PATCH V14 00/18] block: support multi-page bvec

From: Sagi Grimberg
Date: Mon Jan 21 2019 - 04:43:29 EST



V14:
- drop patch(patch 4 in V13) for renaming bvec helpers, as suggested by Jens
- use mp_bvec_* as multi-page bvec helper name
- fix one build issue, which is caused by missing one converion of
bio_for_each_segment_all in fs/gfs2
- fix one 32bit ARCH specific issue caused by segment boundary mask
overflow

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++;
--
