Re: SLUB: Return ZERO_SIZE_PTR for kmalloc(0)

No, because as was mentioned earlier in the thread, we want code to be
able to handle 0-sized allocations without special cases.  The goal is
that code like

        buf = kmalloc(nobj * obj_size);
        if (buf == NULL)
                return -ENOMEM;

should work fine if nobj happens to be 0.  But we do want to get an
oops if the code actually tries to read or write *buf.

Aah, missed that part of the discussion. Sorry for the noise ;-)
