[PATCH] BUG() if setscheduler is called from interrupt context
Thomas Gleixner is adding the call to a rtmutex function in setscheduler. This call grabs a spin_lock that is not always protected by interrupts disabled. So this means that setscheduler cant be called from interrupt context. To prevent this from happening in the future, this patch adds a BUG_ON(in_interrupt()) in that function. (Thanks to akpm <aka. Andrew Morton> for this suggestion).
