How do I find/verify, IF and WHEN a specific patch for example this one, have been added to the kernel?
One way I can think off (not very efficient) would be to download all kernels since the patch was logged, and look into change log file. Example:
$ apt-get changelog linux-image-4.4.0-116-generic
How do you approach this type of problems?
apt kernel dpkg patch

One way is to use the a git clone of the source and search for the patch.
Mine is a clone of the mainline source from kernel.org:
git log --oneline | grep "add DISCARD support to virtio-blk driver"
did not find anything. As a sanity check, look at the code itself and manually observe if the patch was ever applied or not. I looked at drivers/block/virtio_blk.c and didn't see the patch.
Conclusion: the patch was never applied to the mainline kernel, and therefore I very much doubt that it would ever have been backported to previous kernels.
