Title:
  Kernel livepatch infrastructure in Ubuntu Server?

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  It has been announced that the livepatch infrastructure has been
  merged to the official Linux kernel tree. This is a system that can
  patch a live kernel without the need for a reboot. It will be
  available on the 3.20 kernel tree.

  Are there any thoughts on implementing this on the Ubuntu Server?

  Sorry for using Bugs for this suggestion but a guy in Answers
  suggested I should talk to you.
