There is module_param_call() - used at least by drivers/md/md.c:
static int get_ro(char *buffer, struct kernel_param *kp) ... static int set_ro(const char *val, struct kernel_param *kp) ... module_param_call(start_ro, set_ro, get_ro, NULL, S_IRUSR|S_IWUSR); [unhandled content-type:application/pgp-signature] | |
