I ran with this patch on three boxes all night, one for 24 hours. No
problems. I stopped the tests, removed the patch, ran the test on the
same boxes and they all crashed within an hour.

This patch definitely fixes the bug.

The test I ran was:

while :; do
 ./ftrace-test-mkinstances || break
 ./ftrace-test-mkinstances-2 || break
done

Note, the tests expect debugfs to be mounted at /debug.
