Subject: Re: [PATCH v2] device-types/blk/description.tex: Allow longer device IDs to be returned
Date: Mon, 7 Sep 2026 19:37:04 +0100 [thread overview]
Message-ID: <20260907183704.GA4240@redhat.com> (raw)

I just noticed that my cover message _didn't_ get sent this time, so
I'll have to reconstruct it ...
In v2:
- Added the feature bit indicating presence of long IDs.
- Define the length of the data field for VIRTIO_BLK_T_GET_LONG_ID.
- Dropped the whole paragraph about compatibility, but added a new
paragraph about suggested length of device IDs.
- Other issues raised by mst in the review should be addressed.
A working implementation of this is here:
