+Subject: [PATCH] virt: vbox: Implement passing requestor info to the host for
+ VirtualBox 6.0.x
+VirtualBox 6.0.x has a new feature where the guest kernel driver passes
+info about the origin of the request (e.g. userspace or kernelspace) to
+the hypervisor.
+If we do not pass this information then when running the 6.0.x userspace
+guest-additions tools on a 6.0.x host, some requests will get denied
+with a VERR_VERSION_MISMATCH error, breaking vboxservice.service and
+the mounting of shared folders marked to be auto-mounted.
+This commit implements passing the requestor info to the host, fixing this.
