Closed vma are protected by the GT wakeref held as we lookup the vma, so we know that the vma will not be freed as we process it for the execbuf. Instead we expect to catch the closed status of the context, and simply allow the close-race on an individual vma to be washed away. Longer term, the GT wakeref protection will be removed by explicit vma.kref tracking.

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.
