Subject: [RFC PATCH v6 09/34] dyndbg: hoist ->site out of ddebug_match_site
Date: Sat, 29 May 2021 14:00:04 -0600 [thread overview]
Message-ID: <20210529200029.205306-10-jim.cromie@gmail.com> (raw)
In-Reply-To: <20210529200029.205306-1-jim.cromie@gmail.com>
A coming change adds _get/_put abstraction on the site pointer, to
allow managing site info more flexibly. The get/put pattern is best
done at a single lexical scope, where its more obviously correct, so
hoist the ->site ref out of ddebug_match_site, and pass it in instead.
no functional changes
