Questions on span_used

[peter-jerry-ye]

Hello,

I'm learning this excellent malloc library. I had a few questions when I read through the code. I wonder if you might help me out?

I see that in the develop branch, there's the span_used linked list for heap, but I think non of the members are turned back to span_partial during rpfree. Is this intentional? Also I think in span_deallocate_block, if a page were a PAGE_HUGE, the memory would get unmapped. Wouldn't that cause the span_used linked list to corrupt from the middle?

Thank you.
