From 8671a5d769b8b1e6f260e4b206b7c658b78daed7 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Thu, 16 Jun 2011 13:16:34 -0700 Subject: Staging: hv: vmbus: Increase the timeout value in the vmbus driver 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.
