From abdb080f7ac8a85547f5e0246362790043bbd3f2 Mon Sep 17 00:00:00 2001 From: Andrey Smetanin Date: Tue, 10 Nov 2015 15:36:31 +0300 Subject: [PATCH] kvm/irqchip: kvm_arch_irq_routing_update renaming split Actually kvm_arch_irq_routing_update() should be kvm_arch_post_irq_routing_update() as it's called at the end of irq routing update. This renaming frees kvm_arch_irq_routing_update function name. kvm_arch_irq_routing_update() weak function which will be used to update mappings for arch-specific irq routing entries (in particular, the upcoming Hyper-V synthetic interrupts).
