From 97577e38284f48ca773392e2d401af2f6c95dc08 Mon Sep 17 00:00:00 2001 From: Pavel Emelyanov Date: Sat, 1 Dec 2007 23:40:40 +1100 Subject: [UNIX]: Extend unix_sysctl_(un)register prototypes Add the struct net * argument to both of them to use in the future. Also make the register one return an error code. It is useless right now, but will make the future patches much simpler. Signed-off-by: Pavel Emelyanov Acked-by: Eric W.
