[PATCH v3 7/8] virtio/s390: use DMA memory for ccw I/O and classic notifiers
...e things. But it ain't
> a big deal.
Two things:
- The call path goes from the vcdev to the vdev, then back to the vcdev
and then to the cdev. Going from the vcdev to the cdev directly
eliminates the roundtrip via the vdev, which I think does not add
anything.
- I prefer
variable = function_returning_a_pointer(...);
over
function_setting_a_variable(..., variable);
The latter obscures the fact that we change the value of the
variable, unless named very obviously.
