Yes, it should probably just be called protect_module_pages and
unprotect_module_pages. The current names provide far too much
information.

But going back a bit, how did we end up with a NULL mod->module_init and
yet module->init_text_size, mod->init_size or mod->init_ro_size
non-zero?

Because if start == end, set_page_attributes() is a noop, right?

Confused,
Rusty.
