Almost there, see below for my comment.

This won't work with dm(raid) partitions as their block sysfs entries are not a subdir
of the containing "disk", they are a (partial) linear device mapping of their containing
disk, so they themselves have a sysfs path of /sys/class/block/dm-# too, just like
their containing disk (but with a higher #)
All I can come up with here, is that you check if the protectedPartition name ends with p#,
and if so strip p#, and then see if what remains matches the name of the dmraid array.
See udev.py: udev_device_get_dmraid_partition_disk(), but that needs udev info for
the partition which you do not have, although we could change its argument, as all it really
needs is the name.
