kconfig: fix to tag NEW symbols correctly
Those configs are not new: $ cat .config ... CONFIG_NAMESPACES=y ... CONFIG_BLOCK=y ... But are tagged as NEW: $ yes "" | make config > myconf $ cat myconf | grep '(NEW)' Namespaces support (NAMESPACES) [Y/?] (NEW) y ... Enable the block layer (BLOCK) [Y/?] (NEW) y ... You can also notice this bug when using gconfig/xconfig. It's because the SYMBOL_DEF_USER bit of an invisible symbol is cleared when the config file is read: int conf_read(const char *name) { ... for_all_symbols(i, sym) { if (sym_has_value(sym) && !sym_is_choice_value(sym)) { /* Reset values of generates values, so they'll appear * as new, if they should become visible, but that * doesn't quite work if the Kconfig and the saved * configuration disagree. */ if (sym->visible == no && !conf_unsaved) sym->flags &= ~SYMBOL_DEF_USER; ... } But a menu item which represents an invisible symbol is still visible, if it's sub-menu is visible, so its SYMBOL_DEF_USER bit should be set to indicate it's not NEW.
