[dm-devel] checkerloop checks too many devices

It seems that checkerloop isn't just checking the your multipathed devices.
It's checking all your devices. Wouldn't it be more sensible to find out which
devices make up part of a multipathed device, and only check those?
Currently, when I start up multipathd, I getting this printed out:
Unknown switch: (null)
multipath v0.4.4 (16/04, 2005)
Usage: /sbin/multipath [-v level] [-d] [-l] [-S]
[-p failover|multibus|group_by_serial|group_by_prio]
[device]
-v level verbosty level
0 no output
1 print created devmap names only
2 default verbosity
3 print debug information
-d dry run, do not create or update devmaps
-l list the current multipath topology
-F flush all multipath device maps
-p policy force all maps to specified policy :
failover 1 path per priority group
multibus all paths in 1 priority group
group_by_serial 1 priority group per serial
group_by_prio 1 priority group per priority lvl
group_by_node_name 1 priority group per target node
device limit scope to the device's multipath
(udev-style $DEVNAME reference, eg /dev/sdb
or major:minor or a device map name)
because checkerloop is trying to check the status of /dev/hda, which is not
multipathed.
