I'm currently prototyping hsch()/csch() support for vfio-ccw, and stumbled over this: We currently expect any I/O to be in command-mode, but don't take care to actively reject transport-mode. This is not an issue with QEMU (which rejects transport-mode ORBs before even the css backend gets to it), but better play safe.
Should we want to support transport-mode in the future, we'll probably need to introduce a capability for it that needs to be enabled by user space.
[I also still have the doc patch from some time ago queued. Let's see if we'll collect more patches.]
