+
+    virt: vbox: Fix VBGL_IOCTL_VMMDEV_REQUEST_BIG and _LOG req numbers to match upstream
+
+    Until this commit the mainline kernel version (this version) of the
+    vboxguest module contained a bug where it defined
+    VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG using
+    _IOC(_IOC_READ | _IOC_WRITE, 'V', ...) instead of
+    _IO(V, ...) as the out of tree VirtualBox upstream version does.
+
+    Since the VirtualBox userspace bits are always built against VirtualBox
+    upstream's headers, this means that so far the mainline kernel version
+    of the vboxguest module has been failing these 2 ioctls with -ENOTTY.
+    I guess that VBGL_IOCTL_VMMDEV_REQUEST_BIG is never used causing us to
+    not hit that one and sofar the vboxguest driver has failed to actually
+    log any log messages passed it through VBGL_IOCTL_LOG.
+
+    This commit changes the VBGL_IOCTL_VMMDEV_REQUEST_BIG and VBGL_IOCTL_LOG
+    defines to match the out of tree VirtualBox upstream vboxguest version,
+    while keeping compatibility with the old wrong request defines so as
+    to not break the kernel ABI in case someone has been using the old
+    request defines.
+
