Method 1: BLKRRPART instead of BLKPG for extended partitions

Package: udisks
Version: 1.0.4-2 (Debian)

When creating a logical partition right after creating the extended one, udisks
(udisks-helper-create-partition) returns with a "Device or resource busy"
error.

Forcing the kernel to reread the partition table right after extended partition
creation or informing the kernel the extended partition is 1KiB long seems to do the trick.

Here is the thread, which led me to the first method:

And here is the source of the second method:

Development focus is on udisks 2.0 and I think we do the right thing there otherwise please reopen. Thanks.
