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

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 a new ..._ATTR helper to allow for this and
annotate one such user in linux/in.h.

-Kees
