From b3cdff10e5e82ba7b99c59ab3089883f6bb85ed8 Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Thu, 24 Oct 2019 13:02:35 +0200 Subject: [PATCH] qapi: Lift features into QAPISchemaEntity Commit 6a8c0b5102 "qapi: Add feature flags to struct types" added features to QAPISchemaObjectType. Commit a95daa5093 "qapi: Add feature flags to commands in qapi" added them to QAPISchemaCommand, duplicating the code. Tolerable, but the duplication will only get worse as we add features to more definitions. To de-duplicate, lift features from QAPISchemaObjectType and QAPISchemaCommand into QAPISchemaEntity.
