3.8.13.18 -stable review patch.  If anyone has any objections, please let me 
know.

------------------

From: Nicolas Dichtel <nicolas.dich...@6wind.com>

[ No relevant upstream commit. ]

This reverts commit 22c3ec552c29cf4bd4a75566088950fe57d860c4.

This patch is not the right fix, it introduces a memory leak when a netns is
destroyed (the FB device is never deleted).
