This isn't necessary if the kernel re-reads the partition table. cfdisk
will notify you if it did not. It only fails if a partition on the disk
is mounted. This is a long-standing kernel bug; the kernel hackers
disagreed on the best way to fix it, so it remains broken. (Actually,
it may be fixed in recent versions).
By the way, if the re-read fails, you can always umount and then run
"sfdisk -R" (or cfdisk and hit W) to try it again. The sfdisk man page
recommends running this before changing your partitions, so you know
whether it will succeed afterwards. Good idea!
