   9           The Sync File Framework adds explicit syncronization via
  10           userspace. It enables send/receive 'struct fence' objects to/from
  11           userspace via Sync File fds for synchronization between drivers via
  12           userspace components. It has been ported from Android.

  14           The first and main user for this is graphics in which a fence is
  15           associated with a buffer. When a job is submitted to the GPU a fence
  16           is attached to the buffer and is transferred via userspace, using Sync
  17           Files fds, to the DRM driver for example. More details at
  18           Documentation/sync_file.txt.
