870b26fa2d Update several example code for newer kernel 
Known issues with current example code:
If you using newer kernel(e.g linux 5.11.x) to compile the example code,
you may meet following error:
1. syscall.c:83:50: error: ‘ksys_close’ undeclared;
2. cryptosk.c:17:24: error: field ‘sg’ has incomplete type
3. cryptosk.c:143:9: error: implicit declaration of function
‘get_random_bytes’
4. error: macro "DECLARE_TASKLET" passed 3 arguments, but takes just 2

Solutions/workaround:
1. In syscall.c, replace #include <linux/syscalls.h> with
#include <linux/fdtable.h> and replace  ksys_close with close_fd
if the kernel version >= 5.11. [1][2]
2. Add #include <linux/scatterlist.h> into cryptosk.c
3. Add #include <linux/random.h> into cryptosk.c
4. In bottomhalf.c and example_tasklet.c, replace DECLARE_TASKLET
with DECLARE_TASKLET_OLD and dispose third argument(0L). [3]

Generate HTML via make4ht (#20) 
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".
