From e1a6af4b000c39148ab407362fcce3ab63b186f2 Mon Sep 17 00:00:00 2001 From: Josh Cartwright Date: Fri, 17 Sep 2021 12:30:55 +0200 Subject: [PATCH] genirq: Update irq_set_irqchip_state documentation On RT kernels, the use of migrate_disable()/migrate_enable() is sufficient to guarantee a task isn't moved to another CPU. Update the irq_set_irqchip_state() documentation to reflect this.
