From a4cf30e15ccea82a07fa5870e8af787b9ea1a672 Mon Sep 17 00:00:00 2001 From: Vitaly Kuznetsov Date: Fri, 30 Oct 2015 12:37:49 +0100 Subject: [PATCH] scsi_scan: don't dump trace when scsi_prep_async_scan() is called twice The only user of scsi_prep_async_scan() is scsi_scan_host() and it handles the situation correctly. Move 'called twice' reporting to debug level as well. The issue is observed on Hyper-V: on any device add/remove event storvsc driver calls scsi_scan_host() and in case previous scan is still running we get the message and stack dump on console.
