[$] Kernel lockdown locked out — for now

As the 4.17 merge window opened, it seemedpossible that the kernel lockdown patch set could be merged at last.That was before the linux-kernel mailing list got its hands on the issue.What resulted was not one of the kernel community's finest moments. But itdid result in a couple of evident conclusions: kernel lockdown will almostcertainly not bemerged for 4.17, but something that looks very much like it is highlylikely to be accepted in a subsequent merge window.
