SLUB, SLOB, and SLQB are all different varients of slab allocators and can 
be chosen as a replacement for SLAB.  SLUB gets the most attention these 
days and is the upstream default.  SLOB is typically used for embedded 
devices and those that require a small memory footprint.  SLQB was a 
development allocator that I believe has been abandoned.
