H A D | irq_work.h | 09089db7 Wed Oct 06 06:18:52 CDT 2021 Sebastian Andrzej Siewior <bigeasy@linutronix.de> irq_work: Also rcuwait for !IRQ_WORK_HARD_IRQ on PREEMPT_RT
On PREEMPT_RT most items are processed as LAZY via softirq context. Avoid to spin-wait for them because irq_work_sync() could have higher priority and not allow the irq-work to be completed.
Wait additionally for !IRQ_WORK_HARD_IRQ irq_work items on PREEMPT_RT.
