Subject: [PATCH 0/7] Batched netns improvements.


This series of patches takes my simple 4k network namespace exit test
from about 44s to 1.6s, with a minuscule increase in code side.

While batching has given me big improvements there are a few
changes in there that improve the performance of cleaning up
a single network namespace.
