The patch titled
     Subject: slub: search partial list on numa_mem_id(), instead of numa_node_id()
has been removed from the -mm tree.  Its filename was
     slub-search-partial-list-on-numa_mem_id-instead-of-numa_node_id.patch

This patch was dropped because it was merged into mainline or a subsystem tree

Subject: slub: search partial list on numa_mem_id(), instead of numa_node_id()

Currently, if allocation constraint to node is NUMA_NO_NODE, we search a
partial slab on numa_node_id() node.  This doesn't work properly on a
system having memoryless nodes, since it can have no memory on that node
so there must be no partial slab on that node.

On that node, page allocation always falls back to numa_mem_id() first. 
So searching a partial slab on numa_node_id() in that case is the proper
solution for the memoryless node case.
