Subject: [PATCH v2 0/2] stddef: Allow attributes to be used when creating flex arrays

v2:
 - don't add a new helper, just add __VA_ARGS__ (Rasmus)
v1: https://lore.kernel.org/all/20240210011452.work.985-kees@kernel.org/

Hi,

We're going to have more cases where we need to apply attributes
(e.g. __counted_by) to struct members that have been declared with
DECLARE_FLEX_ARRAY. Add an optional 3rd argument to allow for this and
annotate one such user in linux/in.h.

I kept the acks/reviews since it's effectively the same...
