Subject: [dpdk-dev] [PATCH 1/9] vhost: fix virtio ready flag check
Date: Thu, 14 May 2020 10:02:10 +0200	[thread overview]
Message-ID: <20200514080218.1435344-2-maxime.coquelin@redhat.com> (raw)
In-Reply-To: <20200514080218.1435344-1-maxime.coquelin@redhat.com>

Before checking whether the device is ready is done
a check on whether the RUNNING flag is set. Then the
READY flag is set if virtio_is_ready() returns true.

While it seems to not cause any issue, it makes more
sense to check whether the READY flag is set and not
the RUNNING one.

Fixes: c0674b1bc898 ("vhost: move the device ready check at proper place")
Cc: stable@dpdk.org
