Subject: [PATCH 2/5] export.h: use __is_defined() to check if __KSYM_* is defined
Date: Tue, 14 Jun 2016 14:58:55 +0900 [thread overview]
Message-ID: <1465883938-25194-2-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1465883938-25194-1-git-send-email-yamada.masahiro@socionext.com>
Here the need is for a macro that checks whether the given symbol is
defined or not, which has nothing to do with config.
The new macro __is_defined() is a better fit for this case.
