[PATCH nvmet-v1 0/1] nvmet: zns: reject full zone report when buffer is too small

[Xixin Liu <liuxixin@kylinos.cn>]

Hi,

A Zone Management Receive partial report (PR bit set) may return fewer zone
descriptors than zones matched.  A full report (PR bit clear) must fit
every matching descriptor in the data buffer.

nvmet already caps Number of Zones on partial reports, but may return success
on a full report when the buffer is too small.  Reject those commands with
INVALID_FIELD.

Tested on nvmet-tcp loopback with io-passthru.

Thanks,
Xixin Liu
