Rusty, the patch "virtio: imply disable_cb on callbacks" is on your tree.
I'd like to figure out how it works: for example:
diff --git a/drivers/block/virtio_blk.c b/drivers/block/virtio_blk.c
--- a/drivers/block/virtio_blk.c
+++ b/drivers/block/virtio_blk.c
@@ -69,6 +69,8 @@ static void blk_done(struct virtqueue *v
/* In case queue is stopped waiting for more buffers. */
blk_start_queue(vblk->disk->queue);
spin_unlock_irqrestore(&vblk->lock, flags);
+
+ vq->vq_ops->enable_cb(vq);
}
static bool do_req(struct request_queue *q, struct virtio_blk *vblk,
Since this does not check the return status from enable_cb,
it seems we could loose an interrupt if it arrives
between poll and callback enable?
Same might apply to other devices.
Thanks,
