Use python3 instead of python in diffconfig Shebang line.
python2 was sunset January 1, 2000 and environments do not need

Just from curiosity, what problem is this solving?
Is there a distribution where 'python' does not exist,
but 'python3' does ?

It is solving the problem that python is long past its life:
https://www.python.org/doc/sunset-python-2/
The 5.11-rc kernel diffconfig doesn't work now due
to the /usr/bin/python change to /usr/bin/env python.
Could we please ensure this makes it into 5.11 and/or
maintains the FIxes tag if it does not?

Yes, Python is finally being removed from some distributions
and has already been done so from my yocto builds where
I detected the problem.

It doesn't look like your change made it into 5.11-rc but I think it should be added?

Ohh, I missed it.
I know many patches are falling into a crack.
To respect the first submitter, and it solves
another file, I just picked up Andy's one.
I use Ubuntu, where /usr/bin/python is a symlink
to /usr/bin/python3.
I just booted Debian in a VM, and confirmed
/usr/bin/python no longer exists.
Thanks for the explanation.

python2 was sunset Jan 1, 2020, not 20 years before that.

Thanks!

JFYI: on some forums / mailing lists it was discussed and Python
people are against this decision in order to prevent python2 script
breakage on Python3 platform due to Python language nature (you may
not notice problem until you got a traceback at some point).

Odd, here:
$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 20.10
Release: 20.10
Codename: groovy
$ ls /usr/bin/python -la
lrwxrwxrwx 1 root root 7 Apr 15 2020 /usr/bin/python -> python2

With the past year: Jan 1, 2020 seems about 20 years ago.

Or maybe it's because my system has only been upgraded since
about Ubuntu 8.04... Maybe it's time for a fresh reinstall..
I believe that Ubuntu now only installs python3 since 18.04
https://wiki.ubuntu.com/BionicBeaver/ReleaseNotes
Other base system changes since 16.04 LTS
The gpg binary is provided by gnupg2
For new installs, a swap file will be used by default instead of a swap partition.
Python 2 is no longer installed by default. Python 3 has been updated to 3.6. This is the last LTS release to include Python 2 in main.

Hmm, presumably I changed the symlink path by myself
although I do not remember... Sorry for confusion.
