What is a -ckt mainline kernel?

  • 772

I just saw v3.16.7-ckt1-utopic on http://kernel.ubuntu.com/~kernel-ppa/mainline/?C=N;O=D and found a related anouncement promising information about -ckt kernels in the ExtendedStable kernel article of the Ubuntu wiki. I don't find any mention of what a -ckt kernel is (substring isn't contained in the wiki article) except if the reference from the announcement means that -ckt is an extended-stable-kernel (feels like too many corners to think around to make the connection to the suffix). Why would v3.16.7-ckt1-utopic be the only -ckt kernel then?

What does -ckt in the version mean?

    "Canonical Kernel Team".

    Found it on the debian mailing list and it also explains why 3.16 is the only kernel at the moment that has it.

    In addition, I would like to announce a change in the kernel numbering scheme that we will be using: we are adding the string '-ckt' ('Canonical Kernel Team') to the kernel version. So, for example, kernel '3.16.7.1' becomes '3.16.7-ckt1'.

    Note that this change applies only to the 3.16 kernel, although in the future we may consider doing it for other kernels we are currently maintaining.

    Cheers, -- Luís
