From 805b5d5e063e7fde5e2eb724e3f4cb18e47cab19 Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Wed, 14 Feb 2007 00:34:11 -0800 Subject: [PATCH] sysctl: factor out sysctl_head_next from do_sysctl The current logic to walk through the list of sysctl table headers is slightly painful and implement in a way it cannot be used by code outside sysctl.c I am in the process of implementing a version of the sysctl proc support that instead of using the proc generic non-caching monster, just uses the existing sysctl data structure as backing store for building the dcache entries and for doing directory reads. To use the existing data structures however I need a way to get at them. [akpm@osdl.org: warning fix] Signed-off-by: Eric W.
