This patchset implements a new 'eh_deadline' attribute to the SCSI host. It will limit the overall SCSI EH runtime by a given timeout. If the timeout expires all intermediate steps will be skipped and host reset will be scheduled immediately. For this patch I've re-used the existing 'last_reset' field of the SCSI host to store the initial time SCSI EH started. Also the field 'resetting' has been removed as it never has been used as intended. As 'last_reset' might be in use by transport-specific EH implementation I've disallowed eh_deadline setting there. Patchset is incremental to my earlier patchset 'scsi: improved eh timeout handler'. As usual, comments etc are welcome.
