Subject: sysctl: remember the ctl_table we passed to register_sysctl_paths
From: Eric W. Biederman <ebiederm@xxxxxxxxxxxx>
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.
