The lttng modules are shipped in Ubuntu as a dkms package which means
they are built directly on your machine for each kernel version you
install. So after adding the required file in your headers you'll need
to rebuild the modules with dkms and unload / reload them in your
running kernel or just reboot the machine.
To rebuild all installed dkms modules for the current kernel:
sudo dkms autoinstall
