Date: Tue, 16 Apr 2013 15:25:50 -0700 From: Haiyang Zhang <haiyangz@...rosoft.com> To: davem@...emloft.net, netdev@...r.kernel.org Cc: haiyangz@...rosoft.com, kys@...rosoft.com, olaf@...fle.de, jasowang@...hat.com, linux-kernel@...r.kernel.org, devel@...uxdriverproject.org Subject: [PATCH net] hyperv: Fix a compiler warning in netvsc_send() Fixed: warning: cast from pointer to integer of different size The Hyper-V hosts always use 64 bit request id. The guests can have 32 or 64 bit pointers which equal to the ulong type size. So we cast it to ulong type. And, assigning 32bit integer to 64 bit variable works fine. The VMBus returns the same id in the completion packet. But the value has no effect on the host side.
