Subject: [PATCH] linux-user: Ignore broken loop ioctl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
During invocations of losetup, we run into an ioctl that doesn't
exist. However, because of that we output an error, which then
screws up the kiwi logic around that call.
So let's silently ignore that bogus ioctl.
