struct func_name_desc {
	/**
	 * Null-terminated symbol name, e.g.
	 * "func" for "mod.submod.func".
	 */
--->	const char *sym;
	/**
	 * Package name, e.g. "mod.submod" for
	 * "mod.submod.func".
	 */
	const char *package;
	/**
	 * A pointer to the last character in ->package + 1.
	 */
	const char *package_end;
};

I marked the address. The structure is not a function name
but consists of two parts - package path and function name
itself and maybe something new will be added in future. So
func_name is suitable for plain names but not for strings
where some part of it has a special meaning with hidden
extension inside, hereby a descriptor. And don't forget
about grepability, without this name change grep returns
a number of irrelevant results.
