From 99b6697a50c2acbe3ca2772d359fc9a28835dc84 Mon Sep 17 00:00:00 2001 From: Bart Van Assche Date: Thu, 10 Oct 2013 13:52:33 +0200 Subject: IB/srp: Avoid offlining operational SCSI devices If SCSI commands are submitted with a SCSI request timeout that is lower than the the IB RC timeout, it can happen that the SCSI error handler has already started device recovery before transport layer error handling starts. So it can happen that the SCSI error handler tries to abort a SCSI command after it has been reset by srp_rport_reconnect(). Tell the SCSI error handler that such commands have finished and that it is not necessary to continue its recovery strategy for commands that have been reset by srp_rport_reconnect().
