b5a78c7127 selftests/overlayfs: verify device and inode numbers in /proc/pid/maps
When mapping a file on overlayfs, the file stored in ->vm_file is a
backing file whose f_inode is on the underlying filesystem. We need to
verify that /proc/pid/maps contains numbers of the overlayfs file, but
not its backing file.
