When I write in fdisk I always get:
	Calling ioctl() to re-read partition table.
and according to the code fdisk calls:
	ioctl(fd, BLKRRPART);

Upon exiting fdisk new partitions are immediately available. IIRC it  
fails with the device is in use -- for example, if I add a partition  
in unallocated space without unmounting an existing partition. That  
generally isn't a problem for me, as I rarely change partitions on the  
boot device, but I can image cases where it is.

Am I abnormal? Or does partprobe call something different so that it  
can re-scan changed partitions even if the device is in use?
