From fd88a4ecd338dacd8024466a42506b34f5762cc8 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Mon, 13 May 2019 00:18:08 +0800 Subject: [PATCH] scsi: qla2xxx: Fix device staying in blocked state commit 2137490f2147a8d0799b72b9a1023efb012d40c7 upstream. This patch fixes issue reported by some of the customers, who discovered that after cable pull scenario the devices disappear and path seems to remain in blocked state. Once the device reappears, driver does not seem to update path to online. This issue appears because of the defer flag creating race condition where the same session reappears. This patch fixes this issue by indicating SCSI-ML of device lost when qlt_free_session_done() is called from qlt_unreg_sess().
