When creating a block device some drivers need to create additional sysfs groups to store driver-specific informations. With the current workflow of adding these groups with a separate call to sysfs after the device has been created we are introducing a race with udev, as the uevent is generated before the sysfs attributes are created, and udev fails to read the required information. This patchset adds a new function 'device_add_disk_with_groups()' and converts the obvious candidates to use this new function. As usual, comments and reviews are welcome.
