Subject: [PATCH 210/329] genirq: update irq_set_irqchip_state documentation
|
|
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/4.19/older/patches-4.19.135-rt60.tar.xz
|
|
|
|
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.
