	linux-mm

This moves those variables to the ".rodata" section which reduces the
kernel size a bit and protects the variables by putting them on
read-only pages at runtime.

What 3 different purposes?

And you sent a patch series that hit a lot of different subsystems and
maintainers all at once, but you didn't cc: all of us.  Who is supposed
to take these?

But step back, _WHY_ are all of these changes needed?  I don't see a
cover letter explaining the rational, and on their own, they really
don't do anything, so it's really confusing as to what is going on here.

thanks,

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 **groups);
> -void driver_remove_groups(struct device_driver *drv, const struct attribute_group **groups);
> +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?

The kernel size should still be the same overall, you are just moving
pointers from one section to another, right?

If not, what are the numbers, show them please.

But step back, are you SURE you can make these attribute group pointers
const?  They are modified by some subsystems by adding or removing items
from the lists, so why does the core need to change for that?

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,

Before this patch series:

   text       data        bss        dec        hex    filename
10645342    6836166    12476420    29957928    1c91f28    vmlinux

After:

   text       data        bss        dec        hex    filename
10645342    6835398    12476420    29957160    1c91c28    vmlinux

(Config attached if you wish to reproduce. I'm using stock GCC from
Debian Bookworm.)

It's only a few hundred bytes, and I havn't really dug deep enough to
explain to you why this is - my goal was (semantic) const-correctness
and .rodata protection, but those numbers are a side effect that
exists.

Some few do modify them, but they do not modify those pointers; they
allocate a new one (the 3 I sbumitted a patch for) or they modify
global variables (arch/pmu) which I'm not going to make "const". But
most globals can indeed be made "const".

The variable gets initialized 3 times with different (unrelated) values:

1. count old rtc->dev.groups
2. count grps
3. allocate new rtc->dev.groups

This coding style is confusing and error prone. The code gets simpler
with this patch, because the cognitive load of understanding a
"count_attribute_groups()" call is lower than reading the "while" loop
and figuring out why it's there.

But I really wrote this patch because after making "rtc->dev.groups"
const, I cannot any longer assign it to "groups", because that
variable must remain non-const.

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.

Shouldn't that live out of the rtc subsystem?

You suggest making this a global function? Sure, if that's preferred,
I'll change it. Whose decision is this?
