Recently, upper-constraints updated eventlet. Unfortunately, there was a bug which breaks our unit tests which was not discovered during the cross-project testing because the affected unit tests require an XFS temp dir. The requirements change has since been reverted, but we ought to have tests that cover the problematic behavior that will actually run as part of cross-project testing. See https://github.com/eventlet/eventlet/pull/826 for the eventlet change that introduced the bug; it has since been fixed on master in https://github.com/eventlet/eventlet/pull/890 (though we still need https://review.opendev.org/c/openstack/swift/+/905796 to be able to work with eventlet master).
