[Crash-utility] [PATCH 1/1] memory: Handle struct slab changes in linux-next

[Alexander Egorenkov]

Since linux-next commit fe1e19081321 ("mm: Split slab into its own type"),
the struct slab is used for both SLAB and SLUB. Therefore, don't depend
on the non-presence of the struct slab to decide whether SLAB implementation
should be chosen and use the member variable "cpu_slab" of the struct
kmem_cache instead, it should be present only in SLUB.
