The eviction process can get into a race condition between the eviction
fence suspend work (which replaces the old fence with new) and kms_close
(which destroys the fence and doesn't expect a new one).
This patch:
- adds a flag to indicate that fd is closing, so fence replacement is
not required (evf_mgr->fd_closing)
- adds a flush_work() during the ev_fence_destroy routine
V2: Addressed review comments from Christian:
- Do not use mutex to sync
- Use flush_work and wait for suspend_work to be done
V3: Fixed state machine for queue->active, which adds into race between
suspend/resume and queue ops

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 reStructuredText 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.
