[dm-devel] [PATCH 1/1] multipath-tools: fix dm- device filtering

[Dragan Stancevic]

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.

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

This change alows the filtering to happen.
