From b0e9d41346a272bbe33ce1da7f7dd015a58747e1 Mon Sep 17 00:00:00 2001 Message-Id: From: Michal Privoznik Date: Tue, 7 Mar 2023 12:02:11 +0100 Subject: [PATCH] qemu: Add @nodemaskRet argument to qemuBuildMemoryBackendProps() While it's true that anybody who's interested in getting .host-nodes attribute value can just use virJSONValueObjectGetArray() (and that's exactly what qemuBuildThreadContextProps() is doing, btw), if somebody is interested in getting the actual virBitmap, they would have to parse the JSON array. Instead, introduce an argument to qemuBuildMemoryBackendProps() which is set to corresponding value used when formatting the attribute.
