The proc_ops structure is defined in <include/linux/proc_fs.h> since
Linux v5.6+.
In older kernels, file_operations structure is used for custom hooks in
/proc file system. However, it contains some members that are unnecessary
in VFS, and every time VFS expands file_operations set, /proc code comes
bloated.
On the other hand, not only the space, but also some operations were
saved by this structure to improve its performance.
This changes the layout to use the default font size with a reasonable
max width and margins around the body. Elements that would overflow on
narrow displays are changed to wrap (.author) or present a scroll bar as
necessary (figure, .verbatim, .fancyvrb). The properties on html and
body are set such that there is no full-document vertical scrolling.
Inline math is displayed in the same size as the surrounding text.
For the example module hello_5, the book showed the incorrect output
in corresponding with its execution results.
In addition, this patch changes from myintArray[2] = {-1, -1} to
myintArray[2] = {420, 420}, which help the readers distinguish from
the kernel messages.
Add a new Github Action to publish to the GitHub page. Use twtug/lkmpg

This patch generates HTML files with "make4ht" in the "html" directory.
Known issues with "make4ht":
Running "make4ht -suf html5 -d html lkmpg.tex" will cause the following
flaws:
1. The layout was unsatisfying.
2. After parsing TeX, it stoped at "\tableofcontents" with errors.
3. Several unneeded files were generated.
4. No way to specify the destination filename for HTML generation.
Solutions/workaround:
1. Use customized configuration file "html.cfg" to specify the layout style.
2. Turn off the \tableofcontents section when using make4ht. However, this
results in the lack of table of contents in HTML. It can be fixed by
appending "\Configure{tableofcontents*}{chapter,section,subsection}"
to configuration file.
3. The build system removes the temporary files.
4. Use a symbolic link "index.html" to "lkmpg.html".
Add a new GitHub Action to build and release the PDF file after every
push to master. Use texlive/texlive docker image for the sake of
reproducibility in preparation for future build tools like make4ht .
Progress #27 - Reproducible TeX build environment using Docker
The device file create in this example is "chardev".
So input command "sudo cat /dev/chardev" will get a valid message
"I already told you %d times Hello world!"
