    …rtial slabs

The current implementation of for_each_allocated_object() is slow as
it iterates through every physical page.

This commit adds the ability to retrieve objects from the per-node
partial lists and the per-cpu partial slab lists, greatly improving
efficiency when searching for the source of vfs caches of dying
cgroups or millions of negative dentries.
