[PATCH blktests 0/4] nvme: add nvmet zone report and FC regression tests

[Andrea Parri]

Add regression tests for three nvmet bugs fixed by the kernel series
"nvmet: fix stale data exposure and ZNS validation" [1]:

  nvme/071  "nvmet-fc: only send read data for successful commands"
  nvme/072  "nvmet: zns: don't leak stale memory in zone management receive"
  nvme/073  "nvmet: zns: reject a NUMD whose byte count wraps"

The nvme/072 fix is already applied to nvme-7.4; the other two are still
under review.

Patch 1 adds the zoned null_blk target setup, cleanup and zone report
status check that nvme/072 and nvme/073 share.  Patches 2-4 add one test
each, with a small C helper for nvme/071 and nvme/072 where nvme-cli
cannot express the check.

All three tests run on every configured transport.  On a kernel without
the fixes, nvme/072 and nvme/073 fail over loop, tcp, rdma and fc, and
nvme/071 fails over fc, the only affected transport.  All three pass
with the fixes applied.

The tests take the next free numbers, nvme/071 to nvme/073.  If other
nvme tests land first, I'm happy to renumber them and resend.
