[PATCH 01/22] kbuild: disable -Wformat-truncation warnings by default
From: Arnd Bergmann <arnd@arndb.de>

Subsystem:
kernel build + files below scripts/ (unless maintained elsewhere), the rest · Maintainers:
Nathan Chancellor, Nicolas Schier, Linus Torvalds
With x86 allmodconfig, we currently get 233 -Wformat-truncation warnings, which makes the entire warnings rather useless. This turns off the warning by default, unless we specify W=1 or higher Signed-off-by: Arnd Bergmann <arnd@arndb.de> --- scripts/Makefile.extrawarn | 3 +++ 1 file changed, 3 insertions(+)
