The fast-path CT could be running as we enter a runtime-suspend or potentially a GT reset, however here we only use the ct->fast_lock and not the full ct->lock. Before disabling the CT, also serialise against the fast_lock to ensure any in-progress work finishes before we start nuking the CT related stuff. Once we disable ct->enabled and drop the lock, any new work should fail gracefully, and anything that was in progress should be finished.

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.
