[PATCH 00/13] IIO: accel/st-sensors move into separate symbol namespaces

[PATCH 00/13] IIO: accel/st-sensors move into separate symbol namespaces

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

https://lwn.net/Articles/760045/ provides a good overview of this feature
and why it might be used.  In this particular case we fall under the multi
module case.  For each group of modules, I've moved the exports into
an independent namespace.

Whilst I'm not entirely sure it is worth the noise of moving the main
IIO exports into a namespace, it is definitely worthwhile for these small
clusters of related modules (typically a core + i2c and spi modules).

I've just done those within drivers/accel (including all of st-sensors as
I did not want to do that piecemeal) as an initial set to get feedback on
what people think of the approach and in particular naming of the namespaces.

As you can see it is a straight forward change to makes so I'll do the
rest of the IIO drivers once we are agreed on the generic details.
Note that I'll be expecting this for any new cases of this pattern going
forwards.

Includes a small diversion in st-sensors where we had a bunch of duplicated
MODULE_* macros for some of the core modules which were made up of multiple
c files.

[PATCH 04/13] iio:accel:bma400: Move exports into BMA400 namespace

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

In order to avoid unnecessary pollution of the global symbol namespace
move the core bma400 functions into a bma400 specific namespace
and import that into the two bus modules.

[PATCH 11/13] iio:accel:fxl8962af: Move exports into FXL8962AF namespace

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

To avoid unnecessary pollution of the global symbol namespace move the
driver core exports into their own namespace and import that into the two
bus modules.

For more info see https://lwn.net/Articles/760045/

[PATCH 12/13] iio:st-sensors: Remove duplicate MODULE_*

[Jonathan Cameron]

From: Jonathan Cameron <Jonathan.Cameron@huawei.com>

The core module and type specific core modules are made up of
several files. There is no benefit in duplicating the MODULE_* macros
in each file so remove them.

Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and
it still worked, making it clear not all of these blocks were needed.

There is a more subtile way to do this. Up to you to judge which you
prefer:

	#define DEFAULT_SYMBOL_NAMESPACE MMA7455

and then use plain EXPORT_SYMBOL_GPL. This way you automatically switch
all export statements in this file. (The #define has to be before
#include <linux/export.h>.)

If you put this into the header near the declaration of the functions
exported in this namespace, you only need one instead of two.

Anyhow, I think this is much a question of personal taste which to
prefer, so understand this mail just as a hint about alternatives, not a
request to change.

Best regards and happy new year,
Uwe

There was some discussion around doing this via makefiles for the CXL
subsystem (I believe it is done with USB for historical reasons) and general
view was that explicit statement was preferred.

https://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl.git/commit/drivers/cxl/core?h=next&id=affec782742e08a7469ef81d7d0a4ae9d1345dfd

Was the outcome of that discussion though right now I can't find
the thread that lead to that patch.

Argument there was that it can be helpful to have it really
obvious in the code that a symbol is only intended for
limited access.

Interesting point on this.  I'm not sure what preferred option will be
and the one thing we want to be is consistent so people know where to
look for these lines.

Let's see if we get any additional opinions on this. So far the only
header in tree that has one of these is the ltc2497 from your series a
while back.  So definitely not common yet...  Early days though ;)

That's clever. Something similar can be done elsewhere in the kernel
too.

Code looks good, but the naming "ST_SENSORS" is not consistent with
existing namespaces already present in the iio subsystem:
12f13d1faead808 ("iio: hid-sensors: lighten exported symbols by moving
to IIO_HID namespace") has introduced IIO_HID_ATTRIBUTES and IIO_HID.

Would IIO_ST make more sense?

It only covers some IIO ST parts. The st_sensors naming is at lest
consistent with the directory.  Could do IIO_ST_SENSORS perhaps?

That then raises the question of whether all the drivers in IIO that
use namespaces should use ones with an IIO prefix?  

IIO_ADIS and IIO_ADXL345 etc

I'm slightly of the view that's overkill where we are matching a part number
but maybe makes sense for the library cases?

Note that HID needed to call out specifically that it as the IIO part
as there is lots of HID stuff elsewhere. That's not true of the
namespaces in this series.

What do you think?

You guys beat me up to it, I also came here to make the very same comment.
