From 8286e96d95f2dd01a72e3500322ad95153a469c2 Mon Sep 17 00:00:00 2001 From: Dexuan Cui Date: Thu, 10 Nov 2016 07:17:48 +0000 Subject: PCI: hv: Use the correct buffer size in new_pcichild_device() We don't really need such a big on-stack buffer. vmbus_sendpacket() here only uses sizeof(struct pci_child_message).
