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
