I printed out the > 'mondo' pa and verified that. Please check this, because that is an implementation detail. We have three SLAB allocators. For example, if the user enables SLOB, I bet you don't get that alignment. The only thing we are universally guaranteed is ARCH_KMALLOC_MINALIGN. Please implement this properly, rather than relying upon things like the above.
