After discussing the the kernel team this seems to be the correct behavior and
output.
This is obviously okay:
"Kernel is locked down from command line; see man kernel_lockdown.7"
but the further msgs like "Lockdown: swapper/0: use of tracefs..." seem to be
right.
Just waiting for another quick test based on the very latest kernel 5.4
from the archives (the one above was from the PPA) and if the output is
similar, we can consider this as done.
