Hello Jason,

Kind of

#define dynamic_pr_debug(fmt, ...) do {					\
	...
		DEBUG_HASH2, __LINE__,					\
		verbose ? _DPRINTK_FLAGS_PRINT : _DPRINTK_FLAGS_DEFAULT}; \
	...

But what if verbose isn't there?

Or something smarter inside dynamic_debug_setup() or
ddebug_add_module() looking for a module symbol or parameter with that
name?

If you'll give me a hint I could probably implement a proposal.
