[Test case]
install both GA and HWE kernels, and
$ sudo apt install dm-writeboost-dkms
then check that the build for both kernels succeeds
[Fix]
Backport the changes from the dm-writeboost-dkms module in Noble to properly support the new 6.8 kernel ABI.
[Regression potential]
System using the dm-writeboost-dkms may experience regressions especially with the new kernel, in that case we may see regressions affecting storage performance.
