[PATCHv5 0/9] block integrity merging and counting

[Keith Busch <kbusch@meta.com>]

From: Keith Busch <kbusch@kernel.org>

Some fixes and cleanups to counting integrity segments when metadata is
used. This addresses merging issues when integrity data is present.

Changes from v3:

  Dropped the trivial nr_integerity_segments helper

  Fixed sg mapping sanity check

  Added reviews

  Fixed commit log typos

Keith Busch (9):
  blk-mq: unconditional nr_integrity_segments
  blk-mq: set the nr_integrity_segments from bio
  blk-integrity: properly account for segments
  blk-integrity: consider entire bio list for merging
  block: provide a request helper for user integrity segments
  scsi: use request to get integrity segments
  nvme-rdma: use request to get integrity segments
  block: unexport blk_rq_count_integrity_sg
  blk-integrity: improved sg segment mapping
