Subject: [PATCH RFC 14/15] libvhost-user: Increase VHOST_USER_MAX_RAM_SLOTS to 4096
Date: Wed, 13 Oct 2021 12:33:29 +0200 [thread overview]
Message-ID: <20211013103330.26869-15-david@redhat.com> (raw)
In-Reply-To: <20211013103330.26869-1-david@redhat.com>
4096 is the maximum we can have right now in QEMU with vhost-user, so
increase the libvhost-user limit as well.
