Subject: [PATCH V3 09/15] vhost: do not export vhost_add_used_n() and vhost_add_used_and_signal_n()
Date: Wed, 17 Jul 2019 06:52:49 -0400 [thread overview]
Message-ID: <20190717105255.63488-10-jasowang@redhat.com> (raw)
In-Reply-To: <20190717105255.63488-1-jasowang@redhat.com>
We would request device to use shadow used ring API. Then there's no
need for exposing those to device.
