From 3eb3a92851857e6de92ad0c57bf7046ac4f58671 Mon Sep 17 00:00:00 2001 From: Hannes Reinecke Date: Thu, 29 Jul 2010 10:10:16 +0200 Subject: [PATCH] [SCSI] Return NEEDS_RETRY for eh commands with status BUSY When the transport is busy and we're sending an EH command drivers occasionally return 'BUSY'. As this in most cases is the TUR command sent as part of the error recovery this is a sure way to make the error recovery escalate. Returning 'NEEDS_RETRY' here will just retry the TUR command and eventually abort the original command, thus making error handling far smoother.
