Tejun Heo 7724abf0ca sched_ext: Make cast_mask() inline
cast_mask() doesn't do any actual work and is defined in a header file.
Force it to be inline. When it is not inlined and the function is not used,
it can cause verificaiton failures like the following:

  # tools/testing/selftests/sched_ext/runner -t minimal
  ===== START =====
  TEST: minimal
  DESCRIPTION: Verify we can load a fully minimal scheduler
  OUTPUT:
  libbpf: prog 'cast_mask': missing BPF prog type, check ELF section name '.text'
  libbpf: prog 'cast_mask': failed to load: -22
  libbpf: failed to load object 'minimal'
  libbpf: failed to load BPF skeleton 'minimal': -22
  ERR: minimal.c:20
  Failed to open and load skel
  not ok 1 minimal #
  =====  END  =====

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.
