ERROR: livepatch kselftest(s) failed
The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.
This patch updates the expected test output to reflect the new log format.

ERROR: livepatch kselftest(s) failed
The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.
This patch updates the expected test output to reflect the new log format.

ERROR: livepatch kselftest(s) failed
The issue arises due to a mismatch in expected log output during livepatch transition. Specifically, the logs previously contained "livepatch:" but have now been updated to "transition:". This results in test failures when comparing the output with the expected values.
This patch updates the expected test output to reflect the new log format.
are you sure? I have just run livepatch selftests on v6.12 and everything was fine.
The above suggests that something happened to KBUILD_MODNAME in your case (which would also mean that the fix should be different). Could you verify or provide more information, please?
