Subject: act_connmark: Remember the struct net instead of guessing it.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a4ffe319ae72034e3f3332698a2fd83b6f063b18;p=linux-beck.git

act_connmark: Remember the struct net instead of guessing it.

Stop guessing the struct net instead of remember it.  Guessing is just
silly and will be problematic in the future when I implement routes
between network namespaces.
