Tested on a 800x480 framebuffer with the following script:
#!/bin/bash
for i in {0..3}
do
((x=$i * 100))
./process-vmalloc 0 $(($i + 1)) $((2000 - $i * 500)) $((($i+1) * 4)) \
$x $x 100 100 &
done

This got pushed back but now after m2m, it's become next task on my list. I
expect to be posting patches in a week or two, hopefully.
I understand that you'd like to make the pointer in the union
ged.
We will be posting cache coherency patches for dma-contig in the near future.

Whether it is a sync before or after the operation can be determined from
the current buffer state: VIDEOBUF_DONE and VIDEOBUF_ERROR indicate a sync
called after an operation.

Add a sanity check to make sure drivers do not adjust the number of buffers
or planes above the supported limit on reqbufs.

Drivers are no longer required to call vb2_buffer_done() for all buffers
they have queued in stop_streaming().
The return value for stop_streaming() has also been removed.
