Package: udisks
Version: 1.0.4-2
Severity: normal
Tags: patch
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 seems to do the trick.
Here is the thread, which led me to this conclusion:
http://www.fedoraforum.org/forum/showthread.php?t=267085
And a similar bug in Ubuntu:
https://bugs.launchpad.net/ubuntu/+source/gnome-disk-utility/+bug/666038
A proposed (tested to some extent) patch attached.

Subject: [PATCH] BLKRRPART instead of BLKPG for extended partitions
Use BLKRRPART instead of BLKPG after creating an extended partition.
BLKPG returns with the "Device or resource busy" error.
