I want that too for some other unrelated patches :) I want request_irq() to use alloc_bootmem when slab is not available so that some low level arch irqs can be requested at init_IRQ() time. (Typically IRQs for cascaded controllers). We currently define statically irqaction structures for them and call setup_irq() on them, this is gross :) Cheers, Ben. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
