From 49a0c45833c9aa9852ba02c9df0f18029509d0a9 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Thu, 18 Oct 2007 03:05:23 -0700 Subject: sysctl: Factor out sysctl_data. There as been no easy way to wrap the default sysctl strategy routine except for returning 0. Which is not always what we want. The few instances I have seen that want different behaviour have written their own version of sysctl_data. While not too hard it is unnecessary code and has the potential for extra bugs. So to make these situations easier and make that part of sysctl more symetric I have factord sysctl_data out of do_sysctl_strategy and exported as a function everyone can use. Further having sysctl_data be an explicit function makes checking for badly formed sysctl tables much easier. Signed-off-by: Eric W.
