Name it after the wrong object and the kernelapplies the relocation when the wrong module loads, or never.The fixture is the first here to honour MODNAME: most hardcodename=vmlinux, so passing -DMODNAME to them silently does nothing and thetest quietly becomes a vmlinux test.This tests the behavior of commit 07f14d6af9d7 ("objtool/klp: Fixcross-module klp relocation section naming").Assisted-by: Claude:claude-opus-4Based-on-test-by: Joe Lawrence <joe.lawrence@redhat.com>Assisted-by: Claude:claude-opus-5Signed-off-by: Song Liu <song@kernel.org>Signed-off-by: Josh Poimboeuf <jpoimboe@kernel.org>Signed-off-by: Ingo Molnar <mingo@kernel.org>Link: https://patch.msgid.link/20260916184351.2720310-29-song@kernel.org List of files: /linux/tools/objtool/tests/generic/fixtures/cross_module.c Wed, 16 Sep 2026 20:43:21 +0200 Song Liu <song@kernel.org>
