bug: "is this a bug or mis-use? "
It always tell me "rmmod module XXX not found",when I use "insmod" and "rmmod".
maybe the variable "info" not consider to using "rmmod" directly?

line:584

code:
>    if (!info) {
>        /* both dirscan and find_alias found nothing */
>        if (applet_name[0] != 'd') /* it wasn't depmod */
>            bb_error_msg("module '%s' not found", name);
>//TODO: _and_die()?
>        goto ret;
>    }

output:
># insmod simple-lkm.ko
>my_module_init called.  Module is now loaded.
># rmmod simple-lkm.ko
>my_module_cleanup called.  Module is now unloaded.
>rmmod module simple-lkm not found

test module file:

          printk(KERN_INFO "my_module_init called.  Module is now loaded.\n");
            return 0;
