scsi: scsi_error: count medium access timeout only once per EH run
The current medium access timeout counter will be increased for each command, so if there are enough failed commands we'll hit the medium access timeout for even a single device failure and the following kernel message is displayed: sd H:C:T:L: [sdXY] Medium access timeout failure. Offlining disk! Fix this by making the timeout per EH run, ie the counter will only be increased once per device and EH run. Fixes: 18a4d0a ("[SCSI] Handle disk devices which can not process medium access commands") Cc: Ewan Milne <emilne@redhat.com> Cc: Lawrence Obermann <loberman@redhat.com> Cc: Benjamin Block <bblock@linux.vnet.ibm.com> Cc: Steffen Maier <maier@linux.vnet.ibm.com> Signed-off-by: Hannes Reinecke <hare@suse.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.
