Fwd: show_interrupts() after free_irq issue 3.10-rc4?
I've been working with device passthrough & irq on armv7 after disassociating the device from guest free_irq() is executed on host. Display of /proc/interrupts still shows the IRQ info with no irq name associated, and there is no irq_action associated with the IRQ. 'show_interrupts()' in 'kernel/irq/proc.c' displays info on the IRQ due to prior stats accumulated. Few other arch specific ones only on irq_action. Is there some specific reason for that? To me it appears misleading to display dormant IRQ info. For the end user - use case like above or unloading driver and seeing the irq show up is confusing as well. Also not sure what you gain by displaying old IRQ info.
