N.b.: if you try to livepatch/trace such a leaf function without
global dependencies, it will crash if that function got called with
a different TOC value. Hence this whole testing.
I am running out of ideas on how to generate this crash, any pointers
will be helpful.
Petr discovered some modular SCSI helper function does it.
