[PATCH] slab: kfree(null) is unlikely

[PATCH] slab: kfree(null) is unlikely
- mark kfree(NULL) as being unlikely

This is just a wild guess, right?

Seems to me, it depends on the code.

More like a judgement based on experience?

If someone is doing kfree(0) with sufficient frequency for this patch to
matter, then they need to stop doing that, rather than pessimising kfree(not 0).
