Subject: [dpdk-stable] [PATCH v3 3/4] vhost: fix unnecessary vring_state_changed call
Date: Tue, 20 Apr 2021 04:57:45 -0400
Message-ID: <1618909066-114980-4-git-send-email-jiayu.hu@intel.com> (raw)
In-Reply-To: <1618909066-114980-1-git-send-email-jiayu.hu@intel.com>

When VHOST_USER_F_PROTOCOL_FEATURES is not negotiated,
there is no need for vhost_user_set_vring_kick() to
notify the application of vring enabled, as
vhost_user_msg_handler() also notifies the application.

This patch is to remove unnecessary vring_state_changed() call.

Fixes: 966027b4b3a3 ("vhost: fix silent queue enabling with legacy guests")
Cc: stable@dpdk.org
