Hi, The instrumentation of a writeback probe was modified in newer 4.19 kernels, a patch [1] to lttng-modules will be required to fix the build. I'll push a stable update but it might take a while to land in buster-updates. In the meantime, you can apply the patch locally or build the modules from the latest 2.10 release tarball which already includes the patch.
