No, for functions that are visible only to the local compilation unit, there's no reason to use "inline". "inline" is just a hint, and modern compilers are smart enough to inline functions when appropriate without a hint, e.g. gcc and clang inline this on all my configurations. Compilers may also ignore the hint, e.g. KASAN=y tends to produce some really amusing results. A longer explanation/rant here: https://lore.kernel.org/all/ZAdfX+S323JVWNZC@xxxxxxxxxx
