Hi Michal,
I've been looking through this code again, and I think your suggestion
will work. I did not realize this iterator already exist:
for_each_free_mem_range() basically iterates through (memory && !reserved)
This is exactly what we need here. So, I will update this patch to use
this

In deferred_init_memmap() where all deferred struct pages are initialized
we have a check like this:
if (page->flags) {
VM_BUG_ON(page_zone(page) != zone);
goto free_range;
}
This way we are checking if the current deferred page has already been
initialized. It
