Returning KMOD_MODULE_COMING instead of KMOD_MODULE_BUILTIN works. The built-in modules are handled by looking at the modules.builtin index file. Is there any chance of returning KMOD_MODULE_COMING for builti-in modules? If it does not have any impact, then the fix should be fine. well... you're not returning KMOD_MODULE_COMING for a builtin module. Having the directory /sys/module/<name> and not the initstate could be either that the module is builtin or that there's a race while loading the module and it's in the coming state. However since we use the index to decide if this module is builtin in the beginning of this function, here it can only be the second case. However... mod->builtin in the beginning of this function is only set if the module is created by a lookup rather than from name or from path.... maybe here we need to actually fallback to the index rather than the cached value, otherwise this test would fail (considering "vt" is builtin): kmod_module_new_from_name(ctx, "vt", &mod); kmod_module_get_initstate(mod, &state); > Do I need to send a separate patch ? I was hoping it would be a oneliner, but it isn't. If you are going to send a patch, please add the necessary checks for the builtin index. Otherwise I can take a look on this until the end of this week. -- Lucas De Marchi -- To unsubscribe from this list: send the line "unsubscribe linux-modules" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
