From d94a86890137fabcc97eaa324bfef3f1827744c8 Mon Sep 17 00:00:00 2001 From: Arputham Benjamin Date: Sat, 5 Sep 2009 20:36:15 -0700 Subject: [PATCH] IB/mthca: Distinguish multiple devices in /proc/interrupts When the mthca driver uses the same name for interrupts for every device in the system. This can make it very confusing trying to work out exactly which device MSI-X interrupts are for. Change the driver to add the PCI name of the device to the interrupt name.
