Subject: [PATCH 0/9] enabled -Wformat-truncation for clang
Date: Tue, 26 Mar 2024 23:37:59 +0100

From: Arnd Bergmann <arnd@arndb.de>

With randconfig build testing, I found only eight files that produce
warnings with clang when -Wformat-truncation is enabled. This means
we can just turn it on by default rather than only enabling it for
"make W=1".

Unfortunately, gcc produces a lot more warnings when the option
is enabled, so it's not yet possible to turn it on both both
compilers.

I hope that the patches can get picked up by platform maintainers
directly, so the final patch can go in later on.
