FYI, from knowing your personally I'm pretty confident you are not part of a conspiracy and you are just doing your best given the context, and I appreciate all your work! I'm a lot less happy about thinks that happen in other groups not involving you directly, and I'm still pretty mad at how the games were played there, and especially other actors the seem to be reading the list here, and instead of taking part in the discussion are causing fuzz in completely unrelated venues. _______________________________________________ Linux-nvme mailing list Linux-nvme@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-nvme
