From b7abcc7df5e131c0b4bf89cb2411c5301ee83d26 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Tue, 5 Nov 2019 07:06:51 -0800 Subject: [PATCH] scsi: qla2xxx: Do command completion on abort timeout commit 71c80b75ce8f08c0978ce9a9816b81b5c3ce5e12 upstream. On switch, fabric and mgt command timeout, driver send Abort to tell FW to return the original command. If abort is timeout, then return both Abort and original command for cleanup.
