From 7fd83f326fb8d0da3f59f704fd6bb27e457aa9df Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Thu, 19 Mar 2015 08:11:34 -0700 Subject: [PATCH] Drivers: hv: vmbus: Don't wait after requesting offers commit 73cffdb65e679b98893f484063462c045adcf212 upstream. Don't wait after sending request for offers to the host. This wait is unnecessary and simply adds 5 seconds to the boot time. Signed-off-by: K. Y.
