Title:
ftrace synthetic_events selftests failure in 5.11
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Hirsute:
Incomplete
Bug description:
[Impact]
The synthetic_events ftrace test is failing in 5.11:
01:58:54 DEBUG| [stdout] # [68] event trigger - test synthetic_events
syntax parser errors [FAIL]
This happens because the synthetic_event parser/syntax has been
reworked in 5.12 and the selftest has been also updated. 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.
