Thank you for the response,
i ended up installing it again,
sudo add-apt-repository ppa:damentz/liquorix && sudo apt-get update
sudo apt-get install linux-image-liquorix-amd64 linux-headers-liquorix-amd64
everything seems to be working fine at the moment with FSYNC enabled once again, still strange as to why it was removed to begin with, anywhere ive been reading is indicating that this is a feature installed with the kernel itself, the last update obviously removed/disabled it somehow .
Cheers.
