+
+ 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.
+
