[Test Plan]
* Run ftrace test from kernel selftests.
[Where problems could occur]
* Only kernel selftests should be affected.
* ftrace test can have false positives or negatives.

Found failing on two hosts for f/aws-5.8:
a1.medium (arm64) - passed on a retrigger, though when the test was ran again (rerun #4), ftracetest once again failed. Seems to be intermittent.
t2.small (amd64) - So far is consistently failing here. Didn't find to be failing on any other amd64 hosts.
