The initial submission went only to linux-scsi, so here it is again with the appropriate cc list. The patches solve the problem of the scsi eh blocking the host until the dev_loss_tmo fires, allowing the scsi eh to stop already when the fast_io_fail_tmo fires. Hannes and Mike agree with this approach. The patches apply to both, the current scsi-misc and the current scsi-rc-fixes tree, i am not quite sure which tree would be more appropriate. -- Christof
