[PATCH v2 0/1] MR425: ntdll: Do not use find_subheap() to find the subheap corresponding to an uncommitted region.

[Zebediah Figura (＠zfigura)]

The commit end of a subheap may be equal to the beginning of another subheap, in
which case find_subheap() will return that one, and we may effectively skip
backwards in the subheap list.

---

There may be a more architecturally palatable way to solve this problem, but
hopefully this is enough to at least demonstrate it.
