Interpreting the radio silence as an unanimous "No, it doesn't", please find tentative fixes/patch (on top of the bpf_acquire_release branch cited in an earlier post) at the bottom of this email. While testing the changes in question, I noticed an (unrelated) omission in the current PPO relation; the second patch below addresses that. Both patches were tested using the "BPF catalogue" available in the tree at stake: as expected, the only differences in outcomes were for the new/added five tests. Please use and integrate according to your preference, any feedback welcome. Andrea
