The counter goes to zero at the start of the parking cycle, but the wakeref itself is held until the end. Likewise, the counter becomes one at the end of the unparking, but the wakeref is taken first. If we check the wakeref instead of the counter, we include the unpark/unparking time as intel_wakeref_is_active(), and do not spuriously declare inactive if we fail to park (i.e. the parking and wakeref drop is postponed).

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.
