Title:
  multipath-tools update introduced syslog messages about partx

Status in multipath-tools package in Ubuntu:
  Fix Released
Status in multipath-tools source package in Xenial:
  Incomplete
Status in multipath-tools package in Debian:
  Fix Released

Bug description:
  [Impact]

   * During "service multipath-tools start" /sbin/multipath is
     called on dm- devices that are filtered but due to a condition
     conf->dev_type == DEV_DEVNODE in filtering code multipath
     binary wasn't dropping out when hitting a dm- device. This
     was due to the fact that in this case conf->dev_type is
     set to DEV_UEVENT. It also happens during a fail-over event.

     This is causing the logs to be filled with following
     messages:

     multipath: dm-6: failed to get udev uid: Invalid argument
     multipath: dm-6: failed to get sysfs uid: Invalid argument
     multipath: dm-6: failed to get sgio uid: No such file or directory

   * Fix should be backported to xenial to avoid more support
     issues being filed.

   * This change alows the filtering to happen.

  [Test Case]

   * install multipath-tools, create a basic multipath.conf with
     dm- filtering rule. Run: "service multipath-tools start"
     and check the log

  [Regression Potential]

   * There should be no regression potential with this change, the filtering
     only allows the code to not traverse the error path.

  
  [Original Description]

  During a path loss event, the syslog is showing these messages where
  prior to the recent upgrade to multipath-tools I didn't see anything
  like this. To me this seems like either a problem or it seems like a
  print message that should go into a different log file.
