Subject: [PATCH v3 8/8] vfio: ccw: Suppressing the BOXED state
Date: Tue, 12 Jun 2018 09:56:50 +0200 [thread overview]
Message-ID: <1528790210-19535-9-git-send-email-pmorel@linux.ibm.com> (raw)
In-Reply-To: <1528790210-19535-1-git-send-email-pmorel@linux.ibm.com>
VFIO_CCW_STATE_BOXED and VFIO_CCW_STATE_BUSY are the same.
Let's only keep one: VFIO_CCW_STATE_BUSY
