Dmitry Osipenko 30b5144ca4 dma-buf/heaps: Don't assert held reservation lock for dma-buf mmapping ... Don't assert held dma-buf reservation lock on memory mapping of exported buffer. We're going to change dma-buf mmap() locking policy such that exporters will have to handle the lock. The previous locking policy caused deadlock problem for DRM drivers in a case of self-imported dma-bufs once these drivers are moved to use reservation lock universally. The problem solved by moving the lock down to exporters. This patch prepares dma-buf heaps for the locking policy update.
