Commit Message

oscar.mateo@intel.com May 9, 2014, 12:08 p.m. UTC 
From: Ben Widawsky <benjamin.widawsky@intel.com>

The name "active" was recommended by Chris.

With the ordering change of how we initialize things, it is desirable to
be able to address each ring, whether initialized or not.

Cc: Chris Wilson <chris@chris-wilson.co.uk>
Signed-off-by: Ben Widawsky <ben@bwidawsk.net>

v2: Several rebases.
