[PATCH 0/3] block: fix bi_vcnt misuse for cloned bio

[Ming Lei <ming.lei@redhat.com>]

Hello Guys,

The 1st patch removes .bi_vcnt from bio_may_need_split() because the
incoming bio may be cloned.

The 2nd patch doesn't initialize cloned bio's bi_vcnt in
bio_iov_bvec_set().

The 3rd patch removes iov iter nr_segs re-calculation for io_import_kbuf().


Ming Lei (3):
  block: fix bio_may_need_split() by using bvec iterator way
  block: don't initialize bi_vcnt for cloned bio in bio_iov_bvec_set()
  io_uring: don't re-calculate iov_iter nr_segs in io_import_kbuf()
