You probably meant the right thing and wrote something else: you should use
'if (IS_ENABLED(CONFIG_SUNRPC_DEBUG)) { ... }' to get that effect, but that
only works within a function. '#if IS_ENABLED(CONFIG_SUNRPC_DEBUG)' is just
a nicer way to write '#if defined(CONFIG_SUNRPC_DEBUG) || 
defined(CONFIG_SUNRPC_DEBUG_MODULE)', which is harmless but pointless here
as the symbol would never be set to 'm'.
