Make sure nested_vmx_hardware_setup/unsetup() are called in pairs under the same conditions. Calling nested_vmx_hardware_unsetup() when nested is false "works" right now because it only calls free_page() on zero- initialized pointers, but it's possible that more code will be added to nested_vmx_hardware_unsetup() in the future.

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.
