In v6.4.0-rc1~143 I've introduced a check that is supposed to return from the function early, if given path is not a dm target. While the idea is still valid, the implementation had a flaw. It calls stat() over given path and the uses major(sb.st_dev) to learn the major of the device. This is then passed to dm_is_dm_major() which returns true or false depending whether the device is under devmapper's control or not. The problem with this approach is in how the major of the device is obtained - paths managed by devmapper are special files and thus we want to be using st_rdev instead of st_dev to obtain the major number. Well, that's what virIsDevMapperDevice() does already so might as well us that.

==============================
Libvirt API for virtualization
==============================
Libvirt provides a portable, long term stable C API for managing the
virtualization technologies provided by many operating systems. It
includes support for QEMU, KVM, Xen, LXC, bhyve, Virtuozzo, VMware
vCenter and ESX, VMware Desktop, Hyper-V, VirtualBox and the POWER
Hypervisor.
For some of these hypervisors, it provides a stateful management
daemon which runs on the virtualization host allowing access to the
API both by non-privileged local users and remote users.
Layered packages provide bindings of the libvirt C API into other
languages including Python, Perl, PHP, Go, Java, OCaml, as well as
mappings into object systems such as GObject, CIM and SNMP.
