Subject: [Qemu-devel] [RFC 1/4] Fix issue affecting get_int32_le() in vmstate.c
Date: Tue, 25 Feb 2014 17:52:47 +0100	[thread overview]
Message-ID: <1393347170-28502-2-git-send-email-a.rigo@virtualopensystems.com> (raw)
In-Reply-To: <1393347170-28502-1-git-send-email-a.rigo@virtualopensystems.com>

The method is not behaving in the way it's supposed to. It should return
the new value only if it's less than the actual one.
