This bug is awaiting verification that the kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed- focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

However, in 5.11 we got only the commit that updates the test without the corresponding rework in the kernel, therefore the test is failing. [Fix] Revert the commit that updates the ftrace synthetic_events selftest. [Test plan] Run the linux ftrace selftest to trigger the problem (e.g., make TARGETS=ftrace kselftests). [Where problems could occur] This fix reverts a test case, if the kernel receives the ftrace rework via stable updates in the future we may see failures with the same test.
