Subject: [PATCH v3 01/21] klp-build: Reject patches to init/*.c
Date: Tue, 12 May 2026 20:33:35 -0700 [thread overview]
Message-ID: <f32864b560d40894cdb70d613480d7c2ecdb55e0.1778642120.git.jpoimboe@kernel.org> (raw)
In-Reply-To: <cover.1778642120.git.jpoimboe@kernel.org>
init/Makefile hard-codes -fno-function-sections and -fno-data-sections,
overriding the klp-build flags needed for patch generation.
Don't allow any changes to those files; being init code they aren't
really patchable anyway.
