Subject: [pve-devel] [PATCH v3 proxmox-backup-qemu 2/3] return version via rust fn instead of header define
Date: Tue, 24 Nov 2020 16:41:21 +0100	[thread overview]
Message-ID: <20201124154122.22202-3-s.reiter@proxmox.com> (raw)
In-Reply-To: <20201124154122.22202-1-s.reiter@proxmox.com>

Otherwise the string gets included in the QEMU binary, not the library.

Suggested-by: Fabian Grünbichler <f.gruenbichler@proxmox.com>
Signed-off-by: Stefan Reiter <s.reiter@proxmox.com>

v3: added, applies as followup on top of already applied one
