Just some fixes and cleanups to counting integrity segments when
metadata is used. This fixes merging issues.

Changes from v2:

  Included all the follow up patches I mentioned in the v2 thread.

  Incorporated Christoph's suggestion to rename blk_rq_count_integrity_sg.

Keith Busch (10):
  blk-mq: set the nr_integrity_segments from bio
  block: provide helper for nr_integrity_segments
  scsi: use request helper to get integrity segments
  nvme-rdma: use request helper to get integrity segments
  block: unexport blk_rq_count_integrity_sg
  blk-integrity: simplify counting segments
  blk-integrity: simplify mapping sg
  blk-integrity: remove inappropriate limit checks
  blk-integrity: consider entire bio list for merging
  blk-merge: properly account for integrity segments
