Bug description:
[Impact]
lttng-modules-dkms is reporting many build errors with linux-hwe-5.11,
because of many kernel ABI changes.
[Fix]
Backporting the individual patches to fix all the build errors would
be a lot of work and the risk to introduce regressions would be pretty
high, therefore it seems safer to update to the version that is also
used in impish, that works with 5.11 and it's backward compatible (so
it works also with 5.4).
[Test]
ubuntu_lttng_smoke_test from (git://kernel.ubuntu.com/ubuntu/autotest-
client-tests)
[Where problems could occur]
This is a major version update, so it does not contain trivial changes
as backporting individual patches/fixes, so there's a risk to see
regressions with lttng (however potential regressions are *only*
limited to lttng).
However, this way is definitely safer than backporting all the
individual changes to fix the all the kernel ABI changes introduced in
5.11.
[Original bug report]
This is a scripted bug report about ADT failures while running lttng-
modules tests for linux-hwe-5.11/5.11.0-20.21~20.04.1 on focal.
Whether this is caused by the dep8 tests of the tested source or the
kernel has yet to be determined.
