New Revision: 222819
URL: http://svn.freebsd.org/changeset/base/222819
Log:
Do not use LCM from stripesize and user specified alignment value.
When user wants have specific alignment - do what user wants.
Use stripesize as alignment value in case, when some of gpart's
arguments are ommitted for automatic calculation.
