[Bug 2043004] Re: lttng-modules-dkms FTBS on jammy with the latest 6.5 kernel

[Timo Aaltonen]

This is on the sru queue already, so doesn't need sponsoring

Also, jammy-proposed has another upload on it for lp2017006. It was
marked as wontfix, so what should we do about these? Just ignore the
older bug?

  [Test case]

   $ sudo apt install lttng-modules-dkms
   $ sudo lttng list -k

  [Fix]

  Backport the changes from mantic to properly support the new 6.5
  kernel ABI.

  [Regression potential]

  We may experience regressions in systems that are using the lttng
  debugging tool with the new 6.5 kernel.
