Title:
  update jbd format for bionic 5.4 backports

Status in lttng-modules package in Ubuntu:
  Won't Fix
Status in lttng-modules source package in Bionic:
  Fix Released

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 for bionic 5.4 backports.

  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 will fail to compile with the error from
  below. The error is from the main focal kernel because the derivates
  for bionic were not cranked yet.

  Regression potential: We may notice new failures in
  ubuntu_lttng_smoke_test once this will compile and run.
