No, I don't think you can do it this way. At a minimum, you'd need to test that the result is word-aligned. Preferably 8-byte aligned. We literally have stuff that knows about these things and uses the low bits in the pointer to keep extra data. (That said, I didn't check whether we actually kmalloc() the data, but I think we do - things like "struct key" etc). Now, maybe those things always have a 8-byte-aligned size, and it works out, but I'd be worried. Of course, there migth be other (even more subtle) cases where we just assume certain alignment, and depend on the fact that we just _happen_ to get it. Who knows..
