From 6fd046f960354250de3fed411eecdb784601bbad Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Wed, 23 Oct 2013 10:51:22 +0200 Subject: [PATCH] [SCSI] scsi_error: Escalate to LUN reset if abort fails If a command abort fails there is a fair chance that all other aborts will be failing, too. So we should be calling LUN reset directly after the first failed abort and skip aborting the remaining commands.
