Usually compilation error or bugs discovered in previous vb2-dma-contig 
patches adding support for dma-buf.

I agree that patches should not break compilation if patches are 
accepted to the mainline. There is a big compilation failure at patch 07 
where videobuf2-dma-contig.c disappears.

Note that these are proof-of-concept patches for support of dma-buf 
exporting/importing dma-buf in V4L2. It would be a waste of time 
polished the patches if they are going to be rejected due to design flaws.
