[Bug 1990232] Re: ubuntu_lttng_smoke_test failed with module build on J-5.15.0-49.55

  Thread Previous • Date Previous • • Thread Next 
Will have to be done at least in focal as well to handle 5.15 backport
kernels. Need to figure out the change which introduces this in case
focal 5.4 kernels do the same. Then bionic needs a new lttng-modules as
well.

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