[PATCH 2/3] Drivers: hv: vmbus: Reduce the delay between retries in vmbus_post_msg()

From: kys
Date: Fri Jul 01 2016 - 17:43:38 EST


From: K. Y. Srinivasan <kys@xxxxxxxxxxxxx>

The current delay between retries is unnecessarily high and is negatively
affecting the time it takes to boot the system.
