I actually often use noinline when developing code simply because it 
makes it easier to read oopses when gcc doesn't inline ever static
(which it normally does if it only has a single caller). You know
roughly where it crashed without having to decode the line number.

I believe others do that too, I notice it's all over btrfs for example.
