A bvec can now consist of multiple physically contiguous pages. This means that bvec_iter_advance() can move to a different page while staying in the same bvec (i.e. ->bi_bvec_done != 0). The messenger works in terms of segments which can now be defined as the smaller of a bvec and a page. The "more bytes to process in this segment" condition holds only if bvec_iter_advance() leaves us in the same bvec _and_ in the same page. On next bvec (possibly in the same page) and on next page (possibly in the same bvec) we may need to set ->last_piece. Signed-off-by: Ilya Dryomov <idryomov@gmail.com> |
