[ Test case ]
Install the latest linux-6.17 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge
Install jool-dkms:
$ sudo apt install jool-dkms
Load the modules:
$ sudo modprobe
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
Apply patch from enabling 6.17
* debian/patches/rename-to-timer_delete_sync-in-Linux-6.15.patch
[ Regression potential ]
We may experience regressions in systems that are using the jool-dkms
drivers, especially with kernels >= 6.8 kernel.
