Subject: [PATCH v8 0/6] iio: new DMABUF based API

Hi Jonathan,

Here's the final(tm) version of the IIO DMABUF patchset.

This v8 fixes the remaining few issues that Christian reported.

I also updated the documentation patch as there has been changes to
index.rst.

This was based on next-20240308.

Changelog:

- [3/6]:
    - Fix swapped fence direction
    - Simplify fence wait mechanism
    - Remove "Buffer closed with active transfers" print, as it was dead
      code
    - Un-export iio_buffer_dmabuf_{get,put}. They are not used anywhere
      else so they can even be static.
    - Prevent attaching already-attached DMABUFs
- [6/6]:
    Renamed dmabuf_api.rst -> iio_dmabuf_api.rst, and updated index.rst
    whose format changed in iio/togreg.

Cheers,
-Paul
