Subject: [PATCH] Makefile.extrawarn: remove -Wnested-externs warning
Date: Tue, 24 Nov 2020 16:43:17 +0100 [thread overview]
Message-ID: <20201124154339.173752-1-arnd@kernel.org> (raw)
From: Arnd Bergmann <arnd@arndb.de>
The -Wnested-externs warning has become useless with gcc, since
this warns every time that BUILD_BUG_ON() or similar macros
are used.
With clang, the warning option does nothing to start with, so
just remove it entirely.
