Subject: [Qemu-devel] [PATCH 15/15] ramblocks: No more being lazy about duplicate names
Date: Wed, 23 Jun 2010 22:42:37 -0600	[thread overview]
Message-ID: <20100624044237.16168.54671.stgit@localhost.localdomain> (raw)
In-Reply-To: <20100624044046.16168.32804.stgit@localhost.localdomain>

Now that we have a working qemu_ram_free() and the primary runtime
user of it has been updated, don't be lenient about duplicate id strings.
We also shouldn't need to create them ondemand at the target.
