Commit 87c9c16317 ("kunit: tool: add support for QEMU") on the 'next'
tree adds 'from __future__ import annotations' in 'kunit_kernel.py'.
Because it is supported on only >=3.7 Python, people using older Python
will get below error:
Traceback (most recent call last):
File "./tools/testing/kunit/kunit.py", line 20, in <module>
import kunit_kernel
File "/home/sjpark/linux/tools/testing/kunit/kunit_kernel.py", line 9
from __future__ import annotations
^
SyntaxError: future feature annotations is not defined
This commit adds a version assertion in 'kunit.py', so that people get
more explicit error message like below:
Traceback (most recent call last):
File "./tools/testing/kunit/kunit.py", line 15, in <module>
assert sys.version_info >= (3, 7), "Python version is too old"
AssertionError: Python version is too old

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.
