From f8572d8f2a2ba75408b97dc24ef47c83671795d7 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 5 Nov 2009 13:32:03 -0800 Subject: sysctl net: Remove unused binary sysctl code Now that sys_sysctl is a compatiblity wrapper around /proc/sys all sysctl strategy routines, and all ctl_name and strategy entries in the sysctl tables are unused, and can be revmoed. In addition neigh_sysctl_register has been modified to no longer take a strategy argument and it's callers have been modified not to pass one.
