I do not think this is fatal if I understood this correctly: https://lore.kernel.org/patchwork/patch/1122097/#1331784 For GCC, we at least get a warning if a function with __always_inline is not inlined. I am fine with adding -Werror=attributes to the top Makefile (unless we have unpleasant side-effects). You filed the bug for Clang, and hopefully it will be OK in the future releases? -- Best Regards Masahiro Yamada
