[PATCH v2 01/15] configfs: make ci_type field, some pointers and function arguments const

[Bhumika Goyal]

The ci_type field of the config_item structure do not modify the fields
of the config_item_type structure it points to. And the other pointers
initialized with ci_type do not modify the fields as well.
So, make the ci_type field and the pointers initialized with ci_type
as const.

Make the struct config_item_type *type function argument of functions
config_{item/group}_init_type_name const as the argument in both the
functions is only stored in the ci_type field of a config_item structure
which is now made const.
Make the argument of configfs_register_default_group const as it is
only passed to the argument of the function config_group_init_type_name
which is now const.

[PATCH v2 03/15] target: make config_item_type const

[Bhumika Goyal]

Make these structures const as they are either passed to the functions
having the argument as const or stored as a reference in the "ci_type"
const field of a config_item structure.

Done using Coccinelle.

[PATCH v2 04/15] iio: make function argument and some structures const

[Bhumika Goyal]

Make the argument of the functions iio_sw{d/t}_group_init_type_name const
as they are only passed to the function config_group_init_type_name having
the argument as const.

Make the config_item_type structures const as they are either passed to
the functions having the argument as const or they are
stored in the const "ci_type" field of a config_item structure.

[PATCH v2 05/15] ocfs2/cluster: make config_item_type const

[Bhumika Goyal]

Make these structures const as they are either passed to the functions
having the argument as const or stored as a reference in the "ci_type"
const field of a config_item structure.

[PATCH v2 09/15] ACPI: configfs: make config_item_type const

[Bhumika Goyal]

Make these structures const as they are either passed to the functions
having the argument as const or stored as a reference in the "ci_type"
const field of a config_item structure.

Done using Coccienlle.

Now we have 9 const instances of the config_item_type structure that are 
identical, with only the .ct_owner field set. Should they be all merged into a 
single structure ?

I think that's a good idea.

But I'm about to slurp up this whole series into my tree, how about making
that an incremental patch?

I'm fine with that.

Bhumika, would you like to submit an incremental patch, or should I do it ?

For various types, there seem to be a few hundred of these, eg:

static const struct hda_pcm_stream alc269_44k_pcm_analog_playback = {
        .rates = SNDRV_PCM_RATE_44100, /* fixed rate */
};

static const struct hda_pcm_stream alc269_44k_pcm_analog_capture = {
        .rates = SNDRV_PCM_RATE_44100, /* fixed rate */
};

Would it be desirable to remove them?  I guess one would have to check
that there are not any pointer equality checks on these values.  Would it
be useful to put a #define to keep the orignal names?

I will submit a patch for merging these structures.
But should I make a separate patch for this particular change or send
a v3 for the whole series?

Thanks,
