This allows passing arrays of const pointers.  The goal is to make
lots of global variables "const" to allow them to live in the
".rodata" section.

In my opinion this touches way too many subsystems in a single patch.
If someting is wrong with just one of the changes, it will be all but
impossible to revert the whole thing.

Also, I don't know why checkpatch is happy with all the

	const struct attribute_group *const*groups;

instead of

	const struct attribute_group *const *groups;

but I still don't like it.

I wasn't sure whether splitting patches was desired. In the past, I
was often asked to fold multiple patches into one. There are so many
opinions :-) but I'll gladly change to whatever is asked.

No. I'll change the coding style (and maybe take some time to fix checkpatch?)

No, checkpatch does not implement a check/warning for this style (see
my other email). There's no rule for this in coding-style.rst. Should
there be one?

Ok, checkpatch support isn't always required, we can notice that changes
like this obviously are not sane and shouldn't be allowed just by
reading them :)

thanks,

My opinion is that const use in the kernel should almost
always have whitespace before and after it except when
preceded by a open parenthesis or a newline.

I totally agree.
