Sure. Thanks.
Since the change got dropped I figured it for a rejection, and that
I would have to rework that patch.
On a similar note. It recently occurred to me that I can make creating
multiple network namespaces depend on !CONFIG_SYSFS. Which will allow
most of the rest of the patches I am sure of to be merged now. And
give me just a little more time to work with Tejun and finish up the
sysfs support.
