Hmm? Is that such a big deal? I think it's worth it for cleanliness, and
kmalloc() should be plenty big enough (a standard 4kB kmalloc on x86 can
cover 4MB worth of vmalloc() space, and anybody who wants to vmalloc more
than than that had better have some good reason for it - and kmalloc()
does actually work for much larger areas too).
So the kmalloc() approach sounds pretty trivial to me.
