From 10bcd47dff496206de68223aeb1a581bccad03d3 Mon Sep 17 00:00:00 2001 From: Jitendra Bhivare Date: Fri, 19 Aug 2016 15:20:13 +0530 Subject: scsi: be2iscsi: Fix to add timer for UE detection UE detection in health check is done in a work scheduled in global wq. UE caused due to transient parity errors are recoverable and reported within 1s. If this check for TPE gets delayed, PF0 might initiate soft-reset and then status of UE recoverable is lost. Handle UE detection in timer routine. Move out EQ delay update work from health check. Make the IOCTL for EQ delay update non-blocking as the completion status is ignored.
