Subject: [PATCH 253/365] 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.
