Commit 87c9c1631788 ("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
