And I want to point that, your page_list_remove_head() with
put_page_and_type_preemptible() ---> ... ---> free_domheap_pages() will
list_del the same page twice.
But I didn't see panic.

Please be more precise - while I don't think there's an issue, I'd like to
understand your concern. Just to clarify: The get_page() at the top of the
outer loop in relinquish_memory() prevents the page currently being processed
from getting passed to free_domheap_pages() - this can only happen at the final
put_page() at the end of the same loop, at which point the page already got
added to a(nother) list.
