From a558dd841d434d95377dadc45c79d1de1b6f8d2d Mon Sep 17 00:00:00 2001 From: Markus Armbruster Date: Mon, 18 Jun 2018 08:43:23 +0200 Subject: [PATCH 16/54] block-qdict: Tweak qdict_flatten_qdict(), qdict_flatten_qlist() RH-Author: Markus Armbruster Message-id: <20180618084330.30009-17-armbru@redhat.com> Patchwork-id: 80725 O-Subject: [RHEL-7.6 qemu-kvm-rhev PATCH 16/23] block-qdict: Tweak qdict_flatten_qdict(), qdict_flatten_qlist() Bugzilla: 1557995 RH-Acked-by: Max Reitz RH-Acked-by: Jeffrey Cody RH-Acked-by: Kevin Wolf qdict_flatten_qdict() skips copying scalars from @qdict to @target when the two are the same. Fair enough, but it uses a non-obvious test for "same". Replace it by the obvious one. While there, improve comments.
