A follow-up to the region-align kernel enabling, [1], update ndctl to
enumerate region alignment, and update the unit tests to account for the
kernel's default compatible alignment.
Given that changing the default is a surefire way to create incompatible
namespaces I do not think it makes sense to plumb region alignment
through the create-namespace interface. Only expert users would be
expected to trawl through sysfs and set a non-default alignment. I.e.
the lack of documentation and enabling for setting this value in the
ndctl man pages is deliberate.
