From: Minfei Huang <mnfhu...@gmail.com>
It is not elegance, if we use function directly as the argument, like
following:
bool each_symbol_section(bool (*fn)(const struct symsearch *arr,
struct module *owner,
void *data), void *data);
Here introduce a type defined function find_symbol_in_section_t. Now
we can use these type defined function directly, if we want to pass
the function as the argument.
bool each_symbol_section(find_symbol_in_section_t fn, void *data);
