It's a complete stupidity that people who have nothing better to
comment about keep throwing at you when you are trying to get stuff
working.

Yes, we should avoid ugly stuff such as

	int rc;
	struct something_very_long foo;

But this definitely should come second to saner ordering such as the
one you propose of grouping related things together. At least IMHO.

You'll notice that the kernel these days attract way more people
interested in commenting to death on various minor points of coding
style than actual worthwhile technical comments on the code.

Cheers,
Ben.
