> Or why not use smp_call_function()?

because the IPI smp_call_function uses might hit between the
MOD_DEC_USE_COUNT that sets the module use count to zero and the
return from module code.  That would mean the interrupted CPU would
return to nonexistent code afterwards and in all likelyhood cause an
Oops.
