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 is reached all intermediate EH 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. Changes from v2: - Escalate to LUN reset if abort fails Changes from the initial version: - Add list_splice_init() calls to avoid stale commands - Rename function to scsi_host_eh_past_deadline Hannes Reinecke (8): dpt_i2o: Remove DPTI_STATE_IOCTL dpt_i2o: return SCSI_MLQUEUE_HOST_BUSY when in reset advansys: Remove 'last_reset' references tmscsim: Move 'last_reset' into host structure dc395: Move 'last_reset' into internal host structure scsi: remove check for 'resetting' scsi: Add 'eh_deadline' to limit SCSI EH runtime scsi_error: Escalate to LUN reset if abort fails drivers/scsi/advansys.c | 8 +-- drivers/scsi/dc395x.c | 24 ++++---- drivers/scsi/dpt_i2o.c | 35 +++++------ drivers/scsi/dpti.h | 1 - drivers/scsi/hosts.c | 7 +++ drivers/scsi/scsi.c | 28 --------- drivers/scsi/scsi_error.c | 146 +++++++++++++++++++++++++++++++++++++++++----- drivers/scsi/scsi_sysfs.c | 37 ++++++++++++ drivers/scsi/tmscsim.c | 14 ++--- drivers/scsi/tmscsim.h | 1 + include/scsi/scsi_host.h | 4 +- 11 files changed, 217 insertions(+), 88 deletions(-) -- 1.8.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
