Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.

...e default domain type and then allocates it for the group. It turned out that this required to remove the calls of iommu_group_get_for_dev() from the IOMMU drivers. While at it, the calls to iommu_device_link()/unlink() where also moved out of the drivers, which required a different interface than add_device()/remove_device(). The result is the new probe_device()/release_device() interface, where the driver just does its own setup and then returns the iommu_device which belongs to the device being probed. There is certainly more room for cleanups, but I think this is a good start to simplify the code...
