Bug Description
Hi.
the following stanza in /etc/multipath.conf
features "2 queue_if_no_path no_partitions"
produces the following error "multipath: Unrecognised multipath feature request" and no devices is visible under /dev/mapper
If the line above is commented out, multipath works ok, although all the partitions within the devices under /dev/mapper are shown. I have also tried using
features "1 no_partitions"
and it didn't work
This configuration is been used in production machines running SLES 11SP3 - SLES 12SP1 and it is working as expected

Could this be something that is included only in a patch in SLES?
I'll look into it, it should be fairly easy to find the relevant patch in git or in SLES packaging.
