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).
