Hi Ingo,

Using WARN_ON_ONCE() or any other code that calls console_lock() from the
process scheduler may trigger lock inversion. This patch series fixes this
by restoring the SCHED_WARN_ON() macro and by changing its implementation.

Please consider this patch series for the next merge window.

Thanks,

Bart.
