I also know that wdata lives longer than wdata->ext so I cannot find
any race condition here. I have checked all four entry points of the
extension-module and they all seem fine here.

As long as wdata->ext is non-NULL, wiiext_schedule may be called. So I
first need to clear wdata->ext before I kill the worker. Otherwise the
worker may be respawned before I reset wdata->ext ;)

Hi,

thank you for the detailed explanation. Could you include a comment
to explain the unusual order things are done in this function?
