I won't be able to get at __cache_alloc() at least until Pekka Enberg layers his "slab: consolidate allocation paths" patches on top of this cpuset memory spread patchset. Indeed, it might be Pekka who does more for __cache_alloc() than me ... that has yet to play out. The entangled, ifdef'd piece of code in mm/slab.c is more convoluted than I can get my head around on this attempt, except for narrowly focused changes. Perhaps Pekka's work and another week will be enough. -- I won't rest till it's the best ...
