[Bug 1896077] Re: lttng-modules-dkms ADT test failure: build error with kernel >= 5.8

 

...actually, looking at the changes, this is a direct backport of the
latest version. I think I'd prefer a bit more work on the SRU bug in
that case, mentioning the possible regression potential etc.

** Also affects: lttng-modules (Ubuntu Focal)
   Importance: Undecided
       Status: New

** Changed in: lttng-modules (Ubuntu Focal)
       Status: New => Incomplete
