SubjectRe: [PATCH 1/1] scsi: storvsc: Reduce default ring buffer size to 128 Kbytes
From
Date

Michael,

> Reduce the default VMbus channel ring buffer size for storvsc SCSI
> devices from 1 Mbyte to 128 Kbytes. Measurements show that ring buffer
> sizes above 128 Kbytes do not increase performance even at very high
> IOPS rates, so don't waste the memory. Also remove the dependence on
> PAGE_SIZE, since the ring buffer size should not change on

Applied to 5.1/scsi-fixes, thanks.
