3.0-stable review patch. If anyone has any objections, please let us know.
------------------ From: "K. Y. Srinivasan" <[email protected]> commit 2dfde9644fe8c4a77f9c73f95b25d6300ca23b5d upstream. On some loaded windows hosts, we have discovered that the host may not respond to guest requests within the specified time (one second) as evidenced by the guest timing out. Fix this problem by increasing the timeout to 5 seconds. It may be useful to apply this patch to the 3.0 kernel as well. Signed-off-by: K. Y.
