The error reported is the following: In file included from /var/lib/dkms/lttng-modules/2.12.2/build/probes/../probes/define_trace.h:87, from /var/lib/dkms/lttng-modules/2.12.2/build/probes/../instrumentation/events/lttng-module/writeback.h:755, from /var/lib/dkms/lttng-modules/2.12.2/build/probes/lttng-probe-writeback.c:38: /var/lib/dkms/lttng-modules/2.12.2/build/probes/../probes/lttng-tracepoint-event-impl.h:131:6: error: conflicting types for ‘trace_writeback_queue_io’ The fix is already available in the upstream git repository. [Test case] Build the dkms package on a >= 5.8 kernel. [Where problems could occur] The upstream lttng-modules project is compatible and buildable on all >3.0 kernels. The new lttng-modules 2.12.2 code should continue to function fine on the 5.4 kernel. I confirmed that the this latest package builds and loads without any errors or warnings on the 5.4 kernel. Therefore, it is more accurate to say there is a small potential for regression on the 5.4 kernel - and that would likely indicate an upstream bug in lttng-modules itself.
