[PATCH 0/2] stddef: Simplify TRAILING_OVERLAP() and improve docs

["Uwe Kleine-König" <u.kleine-koenig@baylibre.com>]

Hello,

as a follup to the discussion I had with Gustavo in reply to
https://lore.kernel.org/linux-pwm/aJtRPZpc-Lv-C6zD@kspp here comes my
suggestion to improve TRAILING_OVERLAP() for wider audience.

While working at it, I wonder if __packed should also better be part of the
macro to ensure that


	struct myfamstruct {
		char c;
		char payload[];
	};

	TRAILING_OVERLAP(struct myfamstruct, mfs, payload,
		unsigned int payload_as_int;
	) fs;

does the right thing. This however is orthogonal and better discussed
separately from this patch set.

Best regards
Uwe
