[PATCH v3 0/2] hw/nvme: support online resize

From: Alexander Mikhalitsyn <[email protected]>

Dear friends,

This patchset is aimed to support online resize for NVMe emulated
device. My approach is simple - I just implement (BlockDevOps *)->resize_cb()
callback and ensure that AER notification is fired to all controllers using
a namespace that is being resized.

Testing.

I manually validated this with Debian 13 VM (a resized disk was a root disk) and
Windows Server 2022 (a resized disk was a secondary one).

Changelog for version 2:
- checkpatch fixes

- CI is green (https://gitlab.com/mihalicyn/qemu/-/pipelines/2602102750)

Kind regards,
Alex
