From f62492bb8d1ea7f7e156ffbdf411de46107072c5 Mon Sep 17 00:00:00 2001 From: Kevin Wolf Date: Mon, 13 Aug 2018 15:23:49 +0200 Subject: block/qapi: Fix memory leak in qmp_query_blockstats() For BlockBackends that are skipped in query-blockstats, we would leak info since commit 567dcb31. Allocate info only later to avoid the memory leak.
