> drm/i915: Beware temporary wedging when determining -EIO
>
> At a few points in our uABI, we check to see if the driver is wedged and
> report -EIO back to the user in that case. However, as we perform the
> check and reset asynchronously (where once before they were both
> serialised by the struct_mutex), we may instead see the temporary wedging
> used to cancel inflight rendering to avoid a deadlock during reset
> (caused by either us timing out in our reset handler,
> i915_wedge_on_timeout or with malice aforethought in intel_reset_prepare
> for a stuck modeset). If we suspect this is the case, that is we see a
> wedged driver *and* reset in progress, then wait until the reset is
> resolved before reporting upon the wedged status.
