Ok sorry, I thought you had a need for some of the features in Giant, using
tunables is probably easier in that case.

However if you do want to upgrade there are debs available:-

http://kernel.ubuntu.com/~kernel-ppa/mainline/

and I believe 3.16 should be available in the 14.04.2 release, which should
be released early next year.

I would rather tune the tunables, as upgrading the kernel would require a
reboot of the client.
Besides, Ubuntu Trusty does not provide a 3.16 kernel, so I would need to
recompile...
