[pve-devel] [PATCH v2 storage 3/6] diskmanage: don't set usage for unused partitions

[Fabian Ebner <f.ebner@proxmox.com>]

The disk type is already 'partition' so there's no additional
information here. And it would need to serve as a code-word for
unused partitions. The cleaner approach is to not set the usage.

No changes from v1.

Was not a smart decision back then...If this is considered a breaking
change for the disk list API call, I'll go for a different approach of
course, but AFAICS it would be one of:
1. Keep usage 'partition', but also return the unused partitions when
'include-partitions=1,type=unused', and have disk_is_used not complain
about usage 'partition'.
2. Add a new type filter/extend it so it can handle multiple types,
i.e. type=unused,partition.
3. Request all disks in the frontend and filter there.
