Subject: Staging: hv: storvsc: Increase the timeout value in the
storvsc driver
From: "K. Y. Srinivasan" <[email protected]>
commit 46d2eb6d82ef44be58ae192c35e8cd52485f02eb 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.
the 3.0 kernel as well.
