Subject: [PATCH 19/27] attr: pass struct attr_check to collect_some_attrs

From: Brandon Williams <[email-masked]>
Date: Thu, 12 Jan 2017 15:53:46 -0800

The old callchain used to take an array of attr_check_item items.
Instead pass the 'attr_check' container object to 'collect_some_attrs()'
and access the fields in the data structure directly.
