Thanks for this Dominik! One question from reading the code: > diff -ruN linux-original/kernel/module.c linux/kernel/module.c > --- linux-original/kernel/module.c 2004-08-01 18:40:25.939948264 +0200 > +++ linux/kernel/module.c 2004-08-01 18:39:01.097846224 +0200 > @@ -1131,6 +1131,12 @@ > }; > static decl_subsys(module, &module_ktype, NULL); > > +extern int module_param_sysfs_setup(struct module *mod, > + struct kernel_param *kparam, > + unsigned int num_params); > + > +extern void module_param_sysfs_remove(struct module *mod); Put these in moduleparam.h please, otherwise AKPM will kill us both. > + kbuild_modname = kmalloc(sizeof(char) * (MAX_KBUILD_MODNAME + 1), GFP_KERNEL); > + if (!kbuild_modname) > + return -ENOMEM; > + memset(kbuild_modname, 0, sizeof(char) * (MAX_KBUILD_MODNAME + 1)); ... > + kfree (kbuild_modname); I would have thought this a good candidate for a stack variable? > +/* Needs to be before __initcall(module_init) */ > +fs_initcall(param_sysfs_init); That's horrible. And I think the initcall in module.c should be removed in your second patch, no?
