This is used for handling future fences. Currently no driver use these, and I think given the new timeline fence proposed by KHR it would be better to have a more abstract interface for future fences. Could be something simple like a struct dma_future_fence plus a function to add a callback or wait for the fence to materialize. Then syncobj (and anything else really) could grow new functions to expose these two drivers. Normal dma_fence would then keep the nice guarantee that they will always signal (and through ordering, be deadlock free). dma_future_fence would then be the tricky one. This also fixes sphinx complaining about the kerneldoc.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
