From 5c6400536481d9ef44ef94e7bf2c7b8e81534db7 Mon Sep 17 00:00:00 2001 From: Quinn Tran Date: Wed, 26 Sep 2018 22:05:14 -0700 Subject: [PATCH] scsi: qla2xxx: Fix re-using LoopID when handle is in use This patch fixes issue where driver clears NPort ID map instead of marking handle in use. Once driver clears NPort ID from the database, it can reuse the same NPort ID resulting in a PLOGI failure.
