It's actually not valid any more after oslo reports switched to SIGUSR2.
The patch was abandoned but we forgot to alter the bug report, sorry
about that.

Title:
  Prefix Delegation pd-notify command uses SIGUSR1, which is now used by
  Guru Mediation Report

Status in neutron:
  Invalid

Bug description:
  The neutron-pd-notify command has been failing since December 9th due
  to [1]. In addition to [1], patch [2] highlighted a conflict between
  oslo_reports and neutron-pd-notify both using SIGUSR1

  pd-notify was changed from using SIGHUP to using SIGUSR1 by
  https://review.openstack.org/#/c/240267/

  We can't go back to using SIGHUP without breaking the l3-agent restart
  function, so I would suggest using another currently unused signal
  such as SIGCHLD.

  Without neutron-pd-notify, neutron cannot learn of prefix updates
  received by the pd client.
