that appears to be the result of:
$ grep -r __module_param_call * drivers/usb/core/usb.c:__module_param_call("", nousb, param_set_bool, param_get_bool, &nousb, 0444); include/linux/moduleparam.h:#define __module_param_call(prefix, name, set, get, arg, perm) \ include/linux/moduleparam.h: __module_param_call(MODULE_PARAM_PREFIX, name, set, get, arg, perm)
and from drivers/usb/core/usb.c:
/* format to disable USB on kernel command line is: nousb */ __module_param_call("", nousb, param_set_bool, param_get_bool, &nousb, 0444);
one has to wonder about the value of a macro that is invoked only once throughout the entire tree.
