Thanks!

The text inside it is just a brief description of s390 specifics,
but the real API descriptions are inside those files:

.. kernel-doc:: arch/s390/include/asm/cio.h
.. kernel-doc:: arch/s390/include/asm/ccwdev.h
.. kernel-doc:: drivers/s390/cio/device.c
.. kernel-doc:: drivers/s390/cio/device_ops.c
.. kernel-doc:: arch/s390/include/asm/cmb.h
.. kernel-doc:: drivers/s390/cio/cmf.c
.. kernel-doc:: arch/s390/include/asm/ccwgroup.h
.. kernel-doc:: drivers/s390/cio/ccwgroup.c
.. kernel-doc:: drivers/s390/cio/airq.c

Those 9 files seem to have been updated lately:

$ git log arch/s390/include/asm/cio.h arch/s390/include/asm/ccwdev.h drivers/s390/cio/device.c drivers/s390/cio/device_ops.c arch/s390/include/asm/cmb.h drivers/s390/cio/cmf.c arch/s390/include/asm/ccwgroup.h drivers/s390/cio/ccwgroup.c drivers/s390/cio/airq.c|grep Date

...

So, I guess that what's there is still valid.

Yet, on a quick grep:

$ git grep -l "/\*\*" drivers/s390/|wc -l
91

So, it seems that only 10% of the kernel-doc markups are actually
documented :-)

Perhaps you could add the missing files there after this patch ;-)


Thanks,
Mauro
