selftests/lkdtm: Don't clear dmesg when running tests 2020-05-08T15:45:50+00:00 Michael Ellerman mpe@ellerman.id.au 2020-05-08T06:53:55+00:00 f131d9edc29d527df4b8f6840c340415f559f095 It is Very Rude to clear dmesg in test scripts. That's because the script may be part of a larger test run, and clearing dmesg potentially destroys the output of other tests. We can avoid using dmesg -c by saving the content of dmesg before the test, and then using diff to compare that to the dmesg afterward, producing a log with just the added lines.
