| |
3.1-stable review patch. If anyone has any objections, please let me know.
------------------
From: Hannes Reinecke <hare@suse.de>
commit 745718132c3c7cac98a622b610e239dcd5217f71 upstream.
When we tear down a device we try to flush all outstanding commands in scsi_free_queue(). However the check in scsi_request_fn() is imperfect as it only signals that we _might start_ aborting commands, not that we've actually aborted some. So move the printk inside the scsi_kill_request function, this will also give us a hint about which commands are aborted.
