From 3239b8cd28fd849a2023483257d35d68c5876c74 Mon Sep 17 00:00:00 2001 From: Shivasharan S Date: Fri, 6 Apr 2018 02:02:11 -0700 Subject: [PATCH] scsi: megaraid_sas: Increase timeout by 1 sec for non-RAID fastpath IOs Hardware could time out Fastpath IOs one second earlier than the timeout provided by the host. For non-RAID devices, driver provides timeout value based on OS provided timeout value. Under certain scenarios, if the OS provides a timeout value of 1 second, due to above behavior hardware will timeout immediately. Increase timeout value for non-RAID fastpath IOs by 1 second.
