Subject: [dpdk-dev] [PATCH v2 1/8] vhost: fix virtio ready flag check
Date: Thu, 2 Jul 2020 10:32:30 +0200 [thread overview]
Message-ID: <20200702083237.1215652-2-amorenoz@redhat.com> (raw)
In-Reply-To: <20200702083237.1215652-1-amorenoz@redhat.com>
From: Maxime Coquelin <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")
