dma_fence_wait_timeout (along with a host of other jiffies-based timeouting functions) returns zero both in case of timeout and when the wait completes during the last jiffy before timeout. As such, we can't rely on it to distinguish between success and timeout. To prevent confusing callers by returning -EAGAIN before the timeout period has elapsed, check if the fence got signaled again after the wait.

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.
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.
