Bug description:
[SRU Justification]
Impact:
Upstream stable added a change in the format of jbd2 in 5.4.229, 5.15.87,
6.1.3.
This is incompatible with the current changes in the lttng-module for
bionic-5.4 backports, focal, jammy, and kinetic.
Focal and bionic updates are needed for the current sru kernel release
(2023.01.30). Both adt and rt fail during compilation of the module.
Jammy and kinetic updates are not needed for this cycle because patches from
upstream stable are not applied yet but it will be needed for the next
release(s).
Correct changes are already in lttng-modules:master and in 2.13.8-1
version.
Fix(es):
1. focal and bionic: Picking 4 patches from upstream lttng-modules which
handle the changed interface as well as add the required code to enable that
change for other versions as well:
LTTNG_KERNEL_RANGE(5,4,229, 5,5,0)
LTTNG_KERNEL_RANGE(5,10,163, 5,11,0)
LTTNG_KERNEL_RANGE(5,15,87, 5,16,0)
LTTNG_KERNEL_RANGE(6,0,18, 6,1,0)
LTTNG_KERNEL_RANGE(6,1,4, 6,2,0)
2. Jammy and kinetic: backport 2.13.8-1
Tescase(s) for focal:
1. lttng-smoke-test fail to compile with the error from below.
2. adt lttng-module fail to compile with same error
Regression potential:
We may notice new failures in ubuntu_lttng_smoke_test once this will compile
and run. But it was tested locally and results were good, so probablity is very
very low.
