6   Nodes _must_ be removed in the exact same order from the scan list as they
7   have been added, otherwise the internal state of the memory manager will be
8   corrupted.
9   </p><p>

11   When the scan list is empty, the selected memory nodes can be freed. An
12   immediately following drm_mm_search_free with !DRM_MM_SEARCH_BEST will then
13   return the just freed block (because its at the top of the free_stack list).
14</p></div><div class="refsect1"><a name="idp1123105924"></a><h2>Returns</h2><p>
15   True if this block should be evicted, false otherwise. Will always
16   return false when no hole has been found.
