- The ctl_name for the kernel directory is CTL_KERN
- It is impoosible to write to sysctl directories so do not
give users write permissions.
This is enough to stop sysctl_check_table from complaining about
the sched debug sysctls.
My apologies for not sending this earlier I had the impression
Ingo's tree had diverged significantly from what was in the
stable tree.
