Subject: [PATCH 0/3] randstruct: gcc-plugin: Remove bogus void member
Date: Sat, 26 Apr 2025 18:38:32 -0700	[thread overview]
Message-ID: <20250427013604.work.926-kees@kernel.org> (raw)

Hi,

Okay, I've tracked down the problem with the randstruct GCC plugin,
and written a KUnit test to validate behaviors. This lets us add
it back the COMPILE_TEST builds.

No need for https://lore.kernel.org/all/20250421000854.work.572-kees@kernel.org/
