Actually, we prepared this patch for a strictly controlled system like Android to easily access the sysfs node for a specific partition like userdata partition using a specific number. In this system, we don't worry about another unexpected f2fs umounter interfering in between unmounting and mounting a partition. When we are under the condition that we can keep track of how many times the userdata partition has been re-mounted, we might as well use the original partition name like "/sys/fs/f2fs/dm-9". This is for when we couldn't do that.
