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

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