Subject: [PATCH 5/6] staging: hv: Increased storvsc ringbuffer and
 max_io_requests

From: Hank Janssen <hjanssen@...rosoft.com>

Increased storvsc ringbuffer and max_io_requests. This now more closely mimics 
the numbers on Hyper-V. And will allow more IO requests to take place for the SCSI driver.
