[PATCH V2 0/2] nvme: Support user mode processing of ZNS Zone Changed AEN

[clay.mayers at kioxia.com]

From: Clay Mayers <clay.mayers at kioxia.com>

This adds support for the ZNS Zone-Descriptor-Changes AEN, which is of
type notify and uses CQE.DW1 to convey the NSID of the log page to read.

Patch 1 adds non-zero NVME_AEN_DATA with the value of CQE.DW1 to all
NVME_AEN uevents.

Patch 2 generates a uevent for all unhandled AEN notify results instead
of issuing a dev warning.

This support is planned to be used by both zone based applications and
another unreleased device with an alternate command set.

Changes since v1
- Break up into two patches
- Only inlucde AEN_DATA if CQE.DW1 is non-zero

Clay Mayers (2):
  nvme: Include AEN CQE.DW1 in NVME_AEN uevents
  nvme: All AENs of type notify generate an NVME_AEN uevent
