Subject: [PATCH 3/3] modpost: move unresolved symbol checks to check_exports()
Date: Fri, 23 Nov 2018 16:57:23 +0900	[thread overview]
Message-ID: <1542959843-16145-3-git-send-email-yamada.masahiro@socionext.com> (raw)
In-Reply-To: <1542959843-16145-1-git-send-email-yamada.masahiro@socionext.com>

This will fit better in check_exports() than add_versions().
