Hello Kees,
While understanding what your patches (I've seen the other ones as well) do themself, I still don't get what your intention is, e.g. why you need this? Apart from a better readability.

Prepare to mark sensitive kernel structures for randomization by making sure they're using designated initializers.
Can you please elaborate what you mean with that sentence?
Hi! Sure: the coming (and optional) gcc plugin "randstruct" performs structure layout randomization, which means that static initializers cannot be "ordered" (they must be "designated"), since the place were layout randomization occurs happens separate from how static initializers are applied.
This change from ordered to designated is just to help the compiler do the right thing.
