[SCSI] scsi: add transport host byte errors (v3) Currently, if there is a transport problem the iscsi drivers will return outstanding commands (commands being exeucted by the driver/fw/hw) with DID_BUS_BUSY and block the session so no new commands can be queued. Commands that are caught between the failure handling and blocking are failed with DID_IMM_RETRY or one of the scsi ml queuecommand return values. When the recovery_timeout fires, the iscsi drivers then fail IO with DID_NO_CONNECT. For fcp, some drivers will fail some outstanding IO (disk but possibly not tape) with DID_BUS_BUSY or DID_ERROR or some other value that causes a retry and hits the scsi_error.c failfast check, block the rport, and commands caught in the race are failed with DID_IMM_RETRY. Other drivers, may hold onto all IO and wait for the terminate_rport_io or dev_loss_tmo_callbk to be called. The following patches attempt to unify what upper layers will see drivers like multipath can make a good guess. This relies on drivers being hooked into their transport class. This first patch just defines two new host byte errors so drivers can return the same value for when a rport/session is blocked and for when the fast_io_fail_tmo fires. The idea is that if the LLD/class detects a problem and is going to block a rport/session, then if the LLD wants or must return the command to scsi-ml, then it can return it with DID_TRANSPORT_DISRUPTED. This will requeue the IO into the same scsi queue it came from, until the fast io fail timer fires and the class decides what to do. When using multipath and the fast_io_fail_tmo fires then the class can fail commands with DID_TRANSPORT_FAILFAST or drivers can use DID_TRANSPORT_FAILFAST in their terminate_rport_io callbacks or the equivlent in iscsi if we ever implement more advanced recovery methods. A LLD, like lpfc, could continue to return DID_ERROR and then it will hit the normal failfast path, so drivers do not have fully be ported to work better. The point of the patches is that upper layers will not see a failure that could be recovered from while the rport/session is blocked until fast_io_fail_tmo/recovery_timeout fires. V3 Remove some comments. V2 Fixed patch/diff errors and renamed DID_TRANSPORT_BLOCKED to DID_TRANSPORT_DISRUPTED. V1 initial patch.
