From: Arun Easi Date: Thu, 16 Jun 2022 05:35:06 +0000 (-0700) Subject: scsi: qla2xxx: Fix losing FCP-2 targets on long port disable with I/Os X-Git-Tag: v5.10.137~100 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=912408ba0bdcefecdca55cae21b8c678b7406722;p=users%2Fdwmw2%2Flinux.git scsi: qla2xxx: Fix losing FCP-2 targets on long port disable with I/Os commit 2416ccd3815ba1613e10a6da0a24ef21acfe5633 upstream. FCP-2 devices were not coming back online once they were lost, login retries exhausted, and then came back up. Fix this by accepting RSCN when the device is not online.
