actually btrfs over lvm over cryptsetup. Guess in that case st_dev in stat does not match mountinfo, so the assumption that mountPtr->deviceId() == buff.st_dev matches at least once is in practice wrong (don't know if this is how it should work or a kernel bug, but the kernel used in my setup is currently 6.2)
