Subject: [PATCH] genirq: Update irq_set_irqchip_state documentation
Git-commit: e1a6af4b000c39148ab407362fcce3ab63b186f2
Patch-mainline: v5.16-rc1
References: bsc#1189998
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.
