Once multipage bvecs is introduced, one bio may hold lots of sectors, and we should always use sort of BIO_MAX_VECS which should be introduced in future and is similiar with current BIO_MAX_PAGES. xfstests(-a auto) have been run and no regression found by this patchset against linus v4.5+. drivers/block/drbd/drbd_int.h | 4 +-- fs/xfs/xfs_buf.c | 2 +- include/linux/bio.h | 55 +------------------------------ include/linux/blk_types.h | 4 +-- include/linux/bvec_iter.h | 77 +++++++++++++++++++++++++++++++++++++++++++ lib/iov_iter.c | 31 +++++++---------- 6 files changed, 94 insertions(+), 79 deletions(-) [1], http://marc.info/?w=2&r=1&s=++[LSF%2FMM+ATTEND]+block%3A+multipage+bvecs&q=t Thanks, Ming
