Public bug reported:

According to the description of the
patch(https://review.opendev.org/c/openstack/neutron/+/637019), every
neutron-server process should names to their role, like:

25355 ?        Ss     0:26 /usr/bin/python /usr/local/bin/neutron-server \
  --config-file /etc/neutron/neutron.conf \
  --config-file /etc/neutron/plugins/ml2/ml2_conf.ini
25368 ?        S      0:00 neutron-server: api worker
25369 ?        S      0:00 neutron-server: api worker
25370 ?        S      0:00 neutron-server: api worker
25371 ?        S      0:00 neutron-server: api worker
25372 ?        S      0:02 neutron-server: rpc worker
25373 ?        S      0:02 neutron-server: rpc worker
25374 ?        S      0:02 neutron-server: services worker

but my devstack environment is:
root@ubuntu:~# ps aux|grep neutron-server

rpc workers process can display the name normally, api workers process
does not display the process name.
