I mean, assuming the BUG_ON bits are bogus, then we should always pass the pointer to the allocator. I audited most of the callers and they all seem to be really just using kmalloc() for allocation anyway.

Isn't this what my original patch did? ;-)

Oh, almost, you had this bit in ksize() of SLAB:

+ if (unlikely(!PageSlab(page)))
+ return PAGE_SIZE << compound_order(page);

Did you actually need it for something?
