In all but one instance, mlock_future_check() is treated as a boolean function despite returning an error code. In one instance, this error code is ignored and replaced with -ENOMEM. This is confusing, and the inversion of true -> failure, false -> success is not warranted. Convert the function to a bool, lightly refactor and return true if the check passes, false if not.

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.
