--- Comment #21 from Thom madeforspam@telfort.nl --- Gilbert, same with me, also ubuntu 14.04 -> 16.04.
The patch is already in the 4.7+ kernel tree so it should be in the first 4.7 kernel (pre) release.
I'm not familiar with ubuntu's kernel policy and I also don't know anyone who does but I guess that the 4.7 kernel will land in 16.10 or 17.04. Best to ask the Ubuntu Kernelteam.
