You're missing:

return NULL;

Ditto.

If you make this one:
return pcalloc_align(pool, n, size, PMALLOC_ALIGN_DEFAULT)
then you don't need the check in this function.
Also, do we really need 'align' as a parameter to the allocator functions
rather than to the pool?
I'd just reuse ARCH_KMALLOC_MINALIGN from slab.h as the alignment, and
then add the special alignment options when we have a real user for them.
