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'm all for doing this type of work, but this is going to be rough.  You
sent patch 6/7 that hit almost all subsystems at once :(

Also, the code:

> +int driver_add_groups(struct device_driver *drv, const struct attribute_group *const*groups);

"*const*groups"?   That's a parsing nightmare, really hard for humans to
read and understand.  Doesn't checkpatch complain about this?

thanks,

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?)

The way to do this right is one-subsystem-at-a-time, right?  Why not
start there, doing it cleanly, and then at the end, change the driver
core and then just the subsystem pointers?  That should be much simpler,
easier to review and verify, and many more changes (and probably take a
kernel release or two to get through.)

thanks,

I found out that checkpatch has no check for this at all; it does
complain about such lines, but only for local variables. But that
warning is actually a bug, because this is a check for unary
operators: it thinks the asterisk is a dereference operator, not a
pointer declaration, and complains that the unary operator must be
preceded by a space. Thus warnings on local variable are only correct
by coincidence, not by design.

Inside structs or parameters (where my coding style violations can be
found), it's a different context and thus checkpatch doesn't apply the
rules for unary operators.

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 :)

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.
