Subject: [Qemu-devel] [PATCH 23/39] memory: make cpu_physical_memory_get_dirty() the main function
Date: Wed,  6 Nov 2013 14:04:32 +0100	[thread overview]
Message-ID: <1383743088-8139-24-git-send-email-quintela@redhat.com> (raw)
In-Reply-To: <1383743088-8139-1-git-send-email-quintela@redhat.com>

And make cpu_physical_memory_get_dirty_flag() to use it.  It used to
be the other way around.
