From 051a60f6a342c83fc489e1533b9f2799fa2b2b9b Mon Sep 17 00:00:00 2001 From: Alberto Garcia Date: Mon, 12 Nov 2018 16:00:38 +0200 Subject: [PATCH] block: Use bdrv_reopen_set_read_only() in qmp_change_backing_file() This patch replaces the bdrv_reopen() calls that set and remove the BDRV_O_RDWR flag with the new bdrv_reopen_set_read_only() function.
