Hi,
I notice that module.h contains stuff like:
#define MODULE_GENERIC_TABLE(gtype,name) \ extern const struct gtype##_id __mod_##gtype##_table \ __attribute__ ((unused, alias(__stringify(name))))
and even:
#define __MODULE_INFO(tag, name, info) \ static const char __module_cat(name,__LINE__)[] \ __attribute_used__ \ __attribute__((section(".modinfo"),unused)) = __stringify(tag) "=" info
My understanding is that we shouldn't be using __attribute__((unused)) in either of these - can someone confirm.
The second one looks fairly dodgy since we're telling a compiler that it's both used and unused. That sounds a bit like a HHGTTG puzzle (you have tea and no tea.)
