kpartx device to image mapping

Question

I am using kpartx to map the paritions of an image file to device mapper. kpartx maps the image to one of the free loop devices, for example, /dev/loop0

Is there a way to query what image is mapped to which device?

for example a command that takes in /dev/loop0 for instance and return the path for the image

The information is available with /sbin/losetup -a.

dmsetup info seems to have no information regarding the backing image – user301916 Sep 15 '15 at 19:11
Sorry for misunderstanding the q. first. – Stefan Paletta Sep 15 '15 at 19:25
no problem. Do you know if the information in losetup -a can be retrieved from the proc fs? or any other file? – user301916 Sep 15 '15 at 19:52
