Subject: [PATCH v3 07/12] block/export: fix blk_size double byteswap
Date: Tue, 23 Feb 2021 14:46:48 +0000	[thread overview]
Message-ID: <20210223144653.811468-8-stefanha@redhat.com> (raw)
In-Reply-To: <20210223144653.811468-1-stefanha@redhat.com>

The config->blk_size field is little-endian. Use the native-endian
blk_size variable to avoid double byteswapping.

Fixes: 11f60f7eaee2630dd6fa0c3a8c49f792e46c4cf1 ("block/export: make vhost-user-blk config space little-endian")
