Doesn't work. I have unpartitioned space at the end of /dev/sda,
but attempting to dmsetup create test --table '0 N linear /dev/sda M'
fails in dm-table:__table_get_device() with -EBUSY. It does seem to
work if the disk in question has no mounted partitions, but that
won't be the case when the disk is in my laptop.
