What's new:
The main changes are support for data striping and *striping-groups*.
striping-groups is a nice option when there are lots of devices in the
system, but the striping of each file is confined to fewer devices, so
not to keep all devices busy on each IO. For example a 10 out of 100
striping means each file is striped across 10 devices out of 100 total
devices in the full system.
Note that exofs has a unique layout structure that enables Mirrors
orthogonal to any striping/raid arrangement.
Next changes will be support for raid5 and raid6
