I don't see any new failures, so I hope it is good this time.  I sort of assume it was a race condition of https://github.com/llvm/llvm-project/pull/125062 landing with https://github.com/llvm/llvm-project/pull/126587 that got rid of a failing test that was not modified in the first PR due to file names being different and messed up.
And then yesterday, I added back the deleted test before this PR: https://github.com/llvm/llvm-project/pull/127685
