Hi Benjamin,
This is a blast from the past since this patch is almost two years old and it
has been languishing in my TODO list for ages. Sorry about that.
Obviously this patch no longer applies, but I was also wondering what exactly
will go wrong if we don't attach to the dma buf.
If something
Until now the only way to make the driver allocate buffers and
share them using dma_buf was to use V4L2_MEMORY_MMAP memory type.
Use of MMAP memory type is a problem because vb2 never call
dma_buf_map_attachment() to attach itself while queuing the buffer
so dma_buf importer will not know that anot
