From a130728554d0cc19ef0ed4c1c824305c1682e64b Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 28 Oct 2021 12:25:16 +0200 Subject: qapi: Generalize struct member policy checking MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The generated visitor functions call visit_deprecated_accept() and visit_deprecated() when visiting a struct member with special feature flag 'deprecated'. This makes the feature flag visible to the actual visitors. I want to make feature flag 'unstable' visible there as well, so I can add policy for it. To let me make it visible, replace these functions by visit_policy_reject() and visit_policy_skip(), which take the member's special features as an argument. Note that the new functions have the opposite sense, i.e. the return value flips.
