whoops, i forgot to ask this as well. accidentally, i returned a positive value from a module_init() routine, which loaded the module and generated in /var/log/messages:
... Jul 4 12:34:43 localhost kernel: hi module being loaded. Jul 4 12:34:43 localhost kernel: sys_init_module: 'hi'->init suspiciously returned 42, it should follow 0/-E convention Jul 4 12:34:43 localhost kernel: sys_init_module: loading module anyway... Jul 4 12:34:43 localhost kernel: Pid: 3881, comm: insmod Tainted: G M 2.6.29.5-191.fc11.x86_64 #1 Jul 4 12:34:43 localhost kernel: Call Trace: Jul 4 12:34:43 localhost kernel: [<ffffffff8106f33b>] sys_init_module+0x13e/0x1cd Jul 4 12:34:43 localhost kernel: [<ffffffff8101133a>] system_call_fastpath+0x16 ... i'd never seen that before, i guess because i never returned a positive error code. is there a tradition for returning positive values? for what purpose? thanks.
