From Linux-5.1 onward, the sysfs interface to send signals to processes stalling livepatch transitions is replace by a peridical signal sent by the kernel. On such systems, the kpatch signal subcommand does nothing. Just let the user know they don't need to worry about it. Fixes: #1151 Signed-off-by: Julien Thierry <jthierry@redhat.com>
