Bug description:
[SRU Justification]
== Impact ==
An upstream change in v5.9 which was backported into all supported releases
modified a function which lltng-modules uses. This causes the DKMS compilation
to fail for all kernels which carry that fix.
== Fix ==
We add kernel version specific fixup code which allows to compile for
previous and newer kernels.
== Testcase ==
DKMS build of lttng-modules will fail without the update and work with all
kernels in updates and proposed.
== Regression Potention ==
The DKMS build might still fail (but beside of conditionally handling an
additional argument to a function the code is unchanged).
