Reserving and checking for space on the g2h side relies on the fast_lock, and not the CT lock since we need to release space from the fast CT path. Make sure we hold it when checking for space and reserving it. The main concern is calling __g2h_release_space() as we are reserving something and since the info.space and info.g2h_outstanding operations are not atomic we can get some nonsense values back.

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.
