Subject: [PATCH 7/8] virt: vbox: Log unknown ioctl requests as error
Date: Wed, 20 May 2020 21:54:39 +0200 [thread overview]
Message-ID: <20200520195440.38759-7-hdegoede@redhat.com> (raw)
In-Reply-To: <20200520195440.38759-1-hdegoede@redhat.com>
Every now and then upstream adds new ioctls without notifying us,
log unknown ioctl requests as an error to catch these.
