[pve-devel] [PATCH qemu-server v5 21/32] backup: future-proof checks for QEMU feature support

[Fiona Ebner]

The features returned by the 'query-proxmox-support' QMP command are
booleans, so just checking for definedness is not enough in principle.
In practice, a feature is currently always true if defined. Still, fix
the checks, should the need to disable support for a feature ever
arise in the future and to avoid propagating the pattern further.
