Date: Thu, 22 Dec 2022 17:54:59 +0200 From: Alvaro Karsz <alvaro.karsz@...id-run.com> To: Jason Wang <jasowang@...hat.com> Cc: mst@...hat.com, davem@...emloft.net, edumazet@...gle.com, kuba@...nel.org, pabeni@...hat.com, virtualization@...ts.linux-foundation.org, netdev@...r.kernel.org, linux-kernel@...r.kernel.org, maxime.coquelin@...hat.com, eperezma@...hat.com Subject: Re: [RFC PATCH 4/4] virtio-net: sleep instead of busy waiting for cvq command My point is that the device may complete the control command after the timeout, so, if I'm not mistaken, next time we send a control command and call virtqueue_wait_for_used we'll get the previous response.
