To elaborate a bit more, this patch only helps evl strictly speaking, by
preventing stdout/err redirections through proxies to cause a kernel
warning, which in fact reveals that some portion of the upstream code
(namely the /null and /zero cdevs at least) are still using a deprecated
file_operations handler, which the VFS complains about when using the
kernel interface to write to them.
