Synchronization is an orthogonal issue to sharing the backing storage of a - buffer and hence should not be handled by dma-buf itself. This is explictly + buffer and hence should not be handled by dma-buf itself. This is explicitly mentioned here because many people seem to want something like this, but if different exporters handle this differently, buffer sharing can fail in interesting ways depending upong the exporter (if userspace starts depending |
