Hi Jonathan,
Here's the final-er version of the IIO DMABUF patchset.
This v9 fixes the few issues reported by the kernel bot.
This was based on next-20240308.
Changelog:
- [3/6]:
- Select DMA_SHARED_BUFFER in Kconfig
- Remove useless forward declaration of 'iio_dma_fence'
- Import DMA-BUF namespace
- Add missing __user tag to iio_buffer_detach_dmabuf() argument
Merge window is coming to an end, and whilst we obviously have plenty of time left in this cycle, I would like to get this queued up fairly early so any issues can shake out and the various series that will build on this can progress.
Hopefully Paul has addressed all remaining comments. So I'm looking for RB or Ack for DMABUF and dmaengine parts from respective reviewers/maintainers.
Thanks
Jonathan
Cheers, -Paul
