From 05d91b557af91fd7870b5d413102e2e902e5a5fc Mon Sep 17 00:00:00 2001 From: Luo Jiaxing Date: Mon, 13 Jul 2020 16:04:30 +0800 Subject: [PATCH] scsi: hisi_sas: Directly trigger SCSI error handling for completion errors Abort failed commands in completion path. This avoids having to wait for block layer timeouts and triggering the SCSI error handling thread.
