Sorry for the super late review, I was swamped. OK so the only issue I can think of is that rmmod *used* to support the kernel wait support with $(rmmod --wait) so wouldn't this be odd?
It is why I had gone with:
-p | --remove-patiently patiently removes the module -t | --timeout timeout in ms to remove the module
You would know better though.
Also just curious, is it really terrible to just support waiting forever?
