[release-notes/stretch] Release notes sign-off from the kernel team

[Niels Thykier <niels@thykier.net>]

Hi,

There is a kernel team related item in the release checklist where we
need input from the you[1]:

Items are:
 * release-notes: KernelTeam signoff for specials with the Kernel

Please review the release notes and file bugs for the missing items (if
any) and let us know once this has been done.

Thanks,
~Niels
