The new umh kill option has allowed kthreads to receive
kill signals but they are generally accepting all sources
of kill signals

And I think this is right,

while the original motivation was to enable
through the OOM from sending the kill.

even if the main concern was OOM.

Users can provide a log output and it should be clear on
the trace what probe / driver got the kill signal.

Well, if you need a WARN output, perhaps you could just add
WARN_ON(fatal_signal_pending()) at the end of load_module() ?

Not only kthread_create() can fail if systemd sends SIGKILL.

Although Oleg had rejected a
similar change a while ago

And honestly, I still dislike this change.

Oleg.
