One could simply specify cache_line_size() with Pekka's patch. cache_line_size() could default to 0 if !SMP. No slab allocator supports that right now. However, SLOB in the past has ignored the alignment in order to reduce memory use. So maybe Matt wants to introduce this? No the slab allocators were optimized for VSMP so that the internode_alignment is not necessary there. That was actually one of the requirements that triggered the slab numa work. --
