The kernel developers did not share there insight into this with me. I'd guess from what I heard from them that SLUB is easier to debug and performing better than the old allocator.

I understand the reasoning why they do not provide special SLAB flavours, though: this would double the number of kernel flavours as every flavour in existence needs to be provided as a SLUB and a SLAB one. Now I already suggested to only provide SLAB flavours for generic variants, but the kernel developers repeatedly called me insane for the call for different flavours where only the memory allocator differs.
