Comment # 13 on bug 1187011 from Lawrence Somerville

Thank you, Larry Finger, for kindly taking some more time to write some more
text here in this ���������thread��������� of postings.  Following your instructions I clicked
on the hyperlink reading ���������fixes_for_leap15.3.patch��������� on the Web page
https://build.opensuse.org/package/show/openSUSE%3AFactory/virtualbox and
subsequently saw 16 lines of what appeared to be code in the C computer
programming language on July 7, 2021.  I found the VirtualBox version 6.1.18
among those lines on July 7, 2021, but surprisingly not ���������VirtualBox 6.1.20���������
among those lines.  Does this mean that VirtualBox 6.1.20 was on July 7, 2021
not yet supported with the necessary backporting of Linux kernel source code in
any version of the Linux kernel released from an openSUSE, online repository,
despite the fact that the software packages virtualbox-guest-x11 and
virtualbox-guest-tools labeled with the number 6.1.20 and very recently 6.1.22
have been available from openSUSE, Leap-15.3 online repositories?  I suppose
that there might be a system, which I don���������t understand or know with certainty,
among the red-, green-, black-, and maybe purple- or violet-colored statements
there.  Due to the appearance of ���������orig��������� and ���������src��������� in the red-colored line
reading ���������---
VirtualBox-6.1.18.orig/src/Vbox/Runtime/r0drv/linux/the-linux-kernel.h���������, I
suppose that that line would mean that you obtained that file named
���������the-linux-kernel.h��������� from Oracle Corporation for its VirtualBox 6.1.18.  Then
in the next, green-colored line reading, ���������+++
VirtualBox-6.1.18/src/Vbox/Runtime/r0drv/linux/the-linux-kernel.h���������, I assume
that the ���������the-linux-kernel.h��������� in that line would include some of your work of
modifying the source-code in the C-language header file ���������the-linux-kernel.h���������. 
And since the file containing such statements is named fixes_for_leap15.3.patch
and within it is titled ���������File fixes_for_leap15.3.patch of Package virtualbox���������
, I assume that the rest of the code in that file is your work.  

I would like something simple for me to do, but for option ���������a��������� perhaps
difficult for you to do.  That is please provide a

a) Linux command I can issue, with a particular kernel version released from an
openSUSE online repository as its argument, that will yield the result of the
version of VirtualBox supported by that Linux kernel for executions of the file
VBoxLinuxAdditions.run obtained from Oracle Corporation,

or else

b) a method from you by which I could look within fixes_for_leap15.3.patch to
see what version of VirtualBox and what version of the Linux kernel released
from an openSUSE repository would be supported for executions of the file
VBoxLinuxAdditions.run obtained from Oracle Corporation, 

or else

c) some other method by which I could learn what version of VirtualBox and what
version of the Linux kernel released from an openSUSE, online repository would
be supported for executions of the file VBoxLinuxAdditions.run obtained from
Oracle Corporation.

Since you are the person now doing the work of backporting code for openSUSE
Leap suitable for VirtualBox computer software, I assume that you could answer
the versions of VirtualBox and the Linux kernel from openSUSE that your work
would support.  So this is a matter of how I could learn the detailed
applicability of your work without my testing an openSUSE kernel version with a
version of VirtualBox from Oracle Corporation by executing a file
VBoxLinuxAdditions.run obtained from Oracle Corporation.
