Subject: [PATCH v3 09/10] qemu/uuid: Add UUID static initializer
Date: Mon, 30 Jan 2023 14:37:04 +0000	[thread overview]
Message-ID: <20230130143705.11758-10-Jonathan.Cameron@huawei.com> (raw)
In-Reply-To: <20230130143705.11758-1-Jonathan.Cameron@huawei.com>

From: Ira Weiny <ira.weiny@intel.com>

UUID's are defined as network byte order fields.  No static initializer
was available for UUID's in their standard big endian format.

Define a big endian initializer for UUIDs.
