From 370d550ea4eda6889ae2fb8a5e9845d2276f1567 Mon Sep 17 00:00:00 2001 From: Arun Easi <arun.easi@qlogic.com> Date: Wed, 22 Aug 2012 14:21:10 -0400 Subject: [PATCH] [SCSI] qla2xxx: Fix for continuous rescan attempts in arbitrated loop topology. Stale information in the temporary fcport created in qla2x00_configure_local_loop() causes qla2x00_get_port_database() call to fail. This reschedules scan, which gets stuck continuously in the rescheduling-of-scan loop due to the failure.
