| Subject: scsi: storvsc: Increase cmd_per_lun for higher speed devices |
| |
| From: "Michael Kelley (EOSG)" <Michael.H.Kelley@microsoft.com> |
| |
| [ Upstream commit cabe92a55e3a12005a4ac4d3954c9a174b0efe2a ] |
| |
| Increase cmd_per_lun to allow more I/Os in progress per device, |
| particularly for NVMe's. The Hyper-V host side can handle the higher |
| count with no issues. |
