/**
 * struct dma_buf_export_sync_file - Get a sync_file from a dma-buf
 *
 * Userspace can perform a DMA_BUF_IOCTL_EXPORT_SYNC_FILE to retrieve the
 * current set of fences on a dma-buf file descriptor as a sync_file.  CPU
 * waits via poll() or other driver-specific mechanisms typically wait on
 * whatever fences are on the dma-buf at the time the wait begins.  This
 * is similar except that it takes a snapshot of the current fences on the
 * dma-buf for waiting later instead of waiting immediately.  This is
 * useful for modern graphics APIs such as Vulkan which assume an explicit
 * synchronization model but still need to inter-operate with dma-buf.
 *
 * The intended usage pattern is the following:
 *
 *  1. Export a sync_file with flags corresponding to the expected GPU usage
 *     via DMA_BUF_IOCTL_EXPORT_SYNC_FILE.
 *
 *  2. Submit rendering work which uses the dma-buf.  The work should wait on
 *     the exported sync file before rendering and produce another sync_file
 *     when complete.
 *
 *  3. Import the rendering-complete sync_file into the dma-buf with flags
 *     corresponding to the GPU usage via DMA_BUF_IOCTL_IMPORT_SYNC_FILE.
 *
 * Unlike doing implicit synchronization via a GPU kernel driver's exec ioctl,
 * the above is not a single atomic operation.  If userspace wants to ensure
 * ordering via these fences, it is the respnosibility of userspace to use
 * locks or other mechanisms to ensure that no other context adds fences or
 * submits work between steps 1 and 3 above.
