Title:
ubuntu_lttng_smoke_test failed with wrong jbd format on 5.4.0-143.160
Status in ubuntu-kernel-tests:
New
Status in lttng-modules package in Ubuntu:

Status in lttng-modules source package in Focal:

Bug description:
[SRU Justification]
Impact: Upstream stable added a change in the format of jbd2 in 5.4.229.
This is incompatible with the current changes in the lttng-module.
Fix: 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)
Tescase: lttng-smoke-test fail to compile with the error from below
Regression potential: We may notice regressions with lttng-modules on kernels
< 5.4.229
