Yes. For the kunit.py output from my previous email, I replaced
CONFIG_DEBUG_KERNEL=y with CONFIG_TRACEPOINTS=y. So, the .kunitconfig I used to
produce the output above was:
CONFIG_KUNIT=y
CONFIG_KUNIT_ALL_TESTS=n
CONFIG_TRACEPOINTS=y
CONFIG_KASAN=y
CONFIG_KASAN_GENERIC=y
CONFIG_KASAN_KUNIT_TEST=y
This more or less mirrors what mm/kfence/.kunitconfig is doing, which also isn't
working on my side; kunit.py reports the same error.
Many thanks,
Paul
