    The removed suppression seems no needed.

    I cannot point the exact commit/PR which makes this change possible.

    Yeah, could have been fixed when switching the clang version from

    to

    FWIW, I’ve checked the TSan task with the focal image before submitting this PR. There were no issues. Perhaps a fix was backported to focal’s clang-10.

    lgtm. The failure rate was low for this one, so even if it still happens, it will take some time to reproduce. I guess this can be merged now and reverted later if it still happens?

    The last change to the Focal LLVM 10 toolchain package was prior to this suppression being added: https://changelogs.ubuntu.com/changelogs/pool/main/l/llvm-toolchain-10/llvm-toolchain-10_10.0.0-4ubuntu1/changelog.

    lgtm. The failure rate was low for this one, so even if it still happens, it will take some time to reproduce.

    Well. It did not take too much time (

    I just fail to reproduce locally. Maybe this only happens with a specific kernel version that Cirrus CI uses?

    Neither do I.

    I’m curious whether https://github.com/llvm/llvm-project/commit/16baf59c6d0b3bf7392995e3e55fc9e2ba9cb5e7 fixes the TSan’s bug? If so, than this PR must be reverted until using clang-15.
