Shrug. Preference I guess... though this is _the_ case for BUG_ON.

I disagree, but OK. I like having the #if marked by the #endif if they
are not close... and elsewhere through the kernel mirrors this. While I
can scroll up and look - assuming the nesting is sane - a simple comment
makes that clear so what is the pain?

Rest looks fine.

Then again, this is all invariants and comments so its really not a big
deal at all. I guess better this than we are fighting over real code,
eh? ;-)
