    genirq: Expose default irq affinity mask (take 3) · 18404756
    Max Krasnyansky authored
    Current IRQ affinity interface does not provide a way to set affinity
    for the IRQs that will be allocated/activated in the future.
    This patch creates /proc/irq/default_smp_affinity that lets users set
    default affinity mask for the newly allocated IRQs. Changing the default
    does not affect affinity masks for the currently active IRQs, they
    have to be changed explicitly.
    
    Updated based on Paul J's comments and added some more documentation.
