The comments for lkdtm_do_action() explicitly call out that it shouldn't be inlined because we want it to show up in stack crawls. However, at least with some compilers / options it's still vanishing due to tail call optimization. Let's add a return value to the function to make it harder for the compiler to do tail call optimization here. Now that we have a return value, we can actually use it in the callers, which is a minor improvement in the code.

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.
