Hi Andrew, Thanks for your feedback, I didn't notice that __maybe_unused is defined repeatedly in selftests directory. Following your suggestions, I've submitted a cleanup patch that centralise the __maybe_unused definition in tools/testing/selftests/kselftest.h and removed the redundant copies across the selftests subdirectories. I've tested it with gcc and clang, and it builds cleanly. Patch Link: https://lore.kernel.org/lkml/20250821101159.2238-1-reddybalavignesh9979@xxxxxxxxx/ Will also look into build system, to tackle including kselftest.h everywhere Thanks, Bala Vignesh
