75 Red zoning and tracking may realign the slab. We can just apply sanity checks
80 Debugging options may require the minimum possible slab order to increase as
82 sizes). This has a higher likelihood of resulting in slab allocation errors
88 You can apply different options to different list of slab names, using blocks
