Well that simplifies the ifdef and allows text editors to still see the
braces as being balanced, at the expense of uglier code for all current
kernel versions. On the other hand this clearly documents the backwards
compatible change for all those kernels and won't affect anything going
forward.
I don't have a strong opinion about either. If I were to choose
however, I'd probably pick Trent's version.
