[Qemu-devel] [PATCH 09/21] block: Fix protocol detection for Windows dev


From: Kevin Wolf
Subject: [Qemu-devel] [PATCH 09/21] block: Fix protocol detection for Windows devices
Date: Fri, 14 May 2010 19:10:43 +0200

We can't assume the file protocol for Windows devices, they need the same
detection as other files for which an explicit protocol is not specified.
