Hi Christian,

Frankly, I think the 'dma_buf' regex is a bit too generic. 'dma_buf'
seems like a reasonable name to me if some subsystem has to deal with
different buffers which can be DMA or non-DMA, like I2C. If you git-grep
the tree, you will find it in quite some places.

We could now think of renaming the variable to 'dmabuf' but this is
a strange and kind of arbitrary rule to remember IMO.

I wonder if you'd miss a lot of patches if we remove 'dma_buf' from the
regex and keep 'dma_fence' and 'dma_resv'? Or extend it to 'dma_buf_' or
'struct dma_buf'?

All the best,

   Wolfram
