From 0b4d414714f0d2f922d39424b0c5c82ad900a381 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 14 Feb 2007 00:34:09 -0800 Subject: [PATCH] sysctl: remove insert_at_head from register_sysctl The semantic effect of insert_at_head is that it would allow new registered sysctl entries to override existing sysctl entries of the same name. Which is pain for caching and the proc interface never implemented. I have done an audit and discovered that none of the current users of register_sysctl care as (excpet for directories) they do not register duplicate sysctl entries. So this patch simply removes the support for overriding existing entries in the sys_sysctl interface since no one uses it or cares and it makes future enhancments harder. Signed-off-by: Eric W.
