Subject: [PATCH AUTOSEL 5.2 57/94] netfilter: conntrack: make sysctls per-namespace again

From: Florian Westphal <fw@...len.de>

[ Upstream commit 478553fd1b6f819390b64a2e13ac756c4d1a2836 ]

When I merged the extension sysctl tables with the main one I forgot to
reset them on netns creation.  They currently read/write init_net settings.

Fixes: d912dec12428 ("netfilter: conntrack: merge acct and helper sysctl table with main one")
Fixes: cb2833ed0044 ("netfilter: conntrack: merge ecache and timestamp sysctl tables with main one")
