From a4f1542af58fd6ab061e594d4e161f1c8b4a4372 Mon Sep 17 00:00:00 2001 From: Stefan Hajnoczi Date: Tue, 23 Feb 2021 14:46:48 +0000 Subject: [PATCH] block/export: fix blk_size double byteswap The config->blk_size field is little-endian. Use the native-endian blk_size variable to avoid double byteswapping.
