Hi Summit,
Sorry for the late review. I know that this code is now in mainline, but I still have a couple of comments. I'll send patches if you agree with them.
Hi Laurent,
Thanks for your review; apologies for being late in replying - I was OoO for last couple of days.
No worries.

Let me know if you'd send patches for these, or should I just go ahead and correct.
I'll send patches.
Another small comment. The map_dma_buf operation is defined as
struct sg_table * (*map_dma_buf)(struct dma_buf_attachment *, enum dma_data_direction);
If we want to let exporters cache the sg_table we should return a const struct sg_table *. unmap_dma_buf will then take a const pointer as well, which would need to be cast to a non-const pointer internally. What's your opinion on that ?
