BTW: The patchset seems to significantly speed up livepatch selftests in tools/testing/selftests/livepatch. I haven't measured it. But I do not longer have to switch screen and do anything else. The transition speed is not our priority. But it is another nice win of this patchset. I only hope that we did not introduce any race ;-) Best Regards, Petr
