Dmitry Osipenko 27f3733a10 dma-buf/heaps: Assert held reservation lock for dma-buf mmapping ... When userspace mmaps dma-buf's fd, the dma-buf reservation lock must be held. Add locking sanity checks to the dma-buf mmaping callbacks to ensure that the locking assumptions won't regress in the future.
