23 The combination of the timeout parameters must be such that SCSI
24 commands are finished in a reasonable time. Hence do not allow the fast
25 I/O fail timeout to exceed SCSI_DEVICE_BLOCK_MAX_TIMEOUT. Furthermore,
26 these parameters must be such that multipath can detect failed paths
27 timely. Hence do not allow all three parameters to be disabled
28 simultaneously.
