Title:
  Multipath 0.8.8 reports High CPU usage when having Lun's using

Bug description:
  When Multipath 0.8.8 to 0.9.3 is used with Ubuntu20.04 and especially
  with 22.04, showing High CPU usage for systemd and multipathd
  processes, making node unresponsive. Multipath 0.9.4 works just fine.
  But as there is no official multipath package for 0.9.4 with Ubuntu
  20.04/22.04, need to compile.

  The ask here is to have 0.9.4 available for Ubuntu 20.04 / 22.04.
  Currently its available for 23.x versions.

  I was able to use the Mantic package repo and install with 22.04 and
  make it work.

  Redhat fixed the same issue and below is the link,

  May be below is the code path having issue
  Seems this impacting 0.8.8 till 0.9.3.
