My question is here? Is that allowed to do because a resize event may
change the order how to iterate over a rhashtable.

Walking over an rhashtable should be a last resort.  There is
no guarantee of stability.

If you skip entries after a resize then you may miss entries.

If you want a stable walk, allocate an extra 8 bytes and use
a linked list.
