From b402f06d6e31b8c3c74bfc3e7d2e292dd4a1b90a Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" <ebiederm@xmission.com> Date: Wed, 14 Feb 2007 00:33:21 -0800 Subject: [PATCH] sysctl: x25: remove unnecessary insert_at_head from register_sysctl_table There has not been much maintenance on sysctl in years, and as a result is there is a lot to do to allow future interesting work to happen, and being ambitious I'm trying to do it all at once :) The patches in this series fall into several general categories. - Removal of useless attempts to override the standard sysctls - Registers of sysctl numbers in sysctl.h so someone else does not use the magic number and conflict. - C99 conversions so it becomes possible to change the layout of struct ctl_table without breaking everything. - Removal of useless claims of module ownership, in the proc dir entries - Removal of sys_sysctl support where people had used conflicting sysctl numbers. Trying to break glibc or other applications by changing the ABI is not cool. 9 instances of this in the kernel seems a little extreme. - General enhancements when I got the junk I could see out. This patch: Since x25 uses unique binary numbers inserting yourself at the head of the search list for sysctls so you can override already registered sysctls is pointless. Signed-off-by: Eric W.

Biederman" <ebiederm@xmission.com> 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.
