| |
This header file provides forward declartion for pgd_lock but does not include the header defining its type. This works since the definition of spinlock_t is usually included somehow via printk.
By trying to avoid recursive includes on PREEMPT_RT I avoided the loop in printk and as a consequnce kernel/intel.c failed to compile due to missing type definition.
Include the needed definition for spinlock_t.
