Umm. What effect does this have? Aren't functions implicitly constant?
What changes as a result of this patch?

My idea was that since all variables of this type are const, we might
as well have the compiler enforce it for the future if you think that
these fields should not be writable at all.
> Aren't functions implicitly constant?
They are, but these are function pointer fields in a structure, not
the functions themselves.

The compiler does already enforce it. We do it like this:
struct address_space {
const struct address_space_operations *a_ops; /* methods */
}

This only ensures that the address_space_operations structure cannot be
written through a_ops, but the address_space_operations structure itself
can still be writable. My patch fixes the latter issue.

The problem with leaving this not const is that a pointer to it is later
assigned to an archdata::dma_ops which you have made into a const pointer
earlier in this patch. This will generate a warning which is fatal in
arch/powerpc as we compile that directory with -Werror.

Actually with a little more work, it can be made const. The only
assignment to it can be put in the initialiser instead ... As an aside,
it should also be made static.

Ok, I made the changes, I also removed the vio_cmo_set_dma_ops function
because I think it is now unnecessary.

It is necessary because vio_dma_mapping_ops is only defined when
CONFIG_PPC_SMLPAR is set, but that function was called from unconditional
code (and there was a trivial version for when CONFIG_PPC_SMLPAR was not
set) i.e. we only want the dma_ops set if we were built with
CONFIG_PPC_SMLPAR.

I think this is the only way to make ptmx_fops const, provided we want to.

Because I saw that checkpatch.pl itself tries to ensure the same I went
through the whole tree looking for non-const file_operations structures
and tried to make them const as best as I could. If you think making
ptmx_fops const is not worth the effort I will remove it from the patch.

Based on the patch, I would think it is not worth it.

Now please break this patch (and your others) out into "one subsystem at

Shall i split them up per subsystem and structure type or
only per subsystem (that is, include all affected structures
in the given subsystem)?

Apart you CCed hundreds of people and mixed thousand things together
into one patch, this makes no sense.
I think the purpose was to not have the fops on multiple places. When
one changes tty_fops, he has to change even ptmx_fops from now on. Not
that I would say the current approach is clean, but this makes it worse IMO.
And as Greg pointed out, you made many functions global for no real income.

I thought that the best way is to have one patch contain changes for
a single structure type only.

Well, if you had per subsystem patches, you would Cc only relevant
people per patch.

The problem is that probably nobody will pick them up. Or you would need
to collect Acks from all participants and run with these to Andrew
Morton. Then it's up to him if he wants to merge them. If you split
them, you can ask concrete maintainers for a merge.

This is ugly and has all marks of cargo-cult patches. NAKed at least
until you give exceptionally good reasons for doing that.

My idea was that since each instance of super_operations is const,
I figured that there is an implicit policy of not wanting writable
super_operations structures in the kernel. If this is actually the
case then my patch makes the compiler enforce this policy, otherwise
please ignore it.
