Ryan Lee 1eadeb462e apparmor: fix boolean argument in apparmor_mmap_file
[ Upstream commit 48d5268e91 ]

The previous value of GFP_ATOMIC is an int and not a bool, potentially
resulting in UB when being assigned to a bool. In addition, the mmap hook
is called outside of locks (i.e. in a non-atomic context), so we can pass
a fixed constant value of false instead to common_mmap.

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 reStructuredText 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.
