[Fix] Upstream lttng 4.14 compat fixes. [Testcase] Without the fix, running the kernel team autotest lttng regression test suite fails because the module does not build and install. With the fix the lttng smoke tests pass. To run the test: sudo autotest/client/autotest-local autotest/client/tests/ubuntu_lttng_smoke_test/control using git://kernel.ubuntu.com/ubuntu/autotest and git://kernel.ubuntu.com/ubuntu/autotest-client-tests [Regression Potential] lttng fails to build and work against older kernels. As the new code is #if'def'd compat code the 4.14 specific changes are not built into the older kernels, so this risk is small. -------------------------------------------------------------------------- [stdout] Setting up lttng-modules-dkms (2.8.0-1ubuntu1~16.04.3) ...
