Subject: [PATCH 0/7] Limit overall SCSI EH runtime
Date: Mon, 10 Jun 2013 13:11:46 +0200 [thread overview]
Message-ID: <1370862713-41323-1-git-send-email-hare@suse.de> (raw)
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.

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
