I always assumed that it was impossible to have the kernel re-read the
partition table of a drive with mounted filesystems.  But apparently it
isn't.  Here's some possibly interesting detail on what partprobe does.

It's possible fdisk doesn't do this.  I don't know enough about parted,
but it's also possible it lets partprobe do it instead of doing it
itself.
