From 23eb06de7d2d333a0f7ebba2da663e00c9c9483e Mon Sep 17 00:00:00 2001 From: "Eric W. Biederman" Date: Fri, 30 Nov 2007 23:52:10 +1100 Subject: [PATCH] sysctl: Remember the ctl_table we passed to register_sysctl_paths By doing this we allow users of register_sysctl_paths that build and dynamically allocate their ctl_table to be simpler. This allows them to just remember the ctl_table_header returned from register_sysctl_paths from which they can now find the ctl_table array they need to free. Signed-off-by: Eric W.
