      [SCSI] lpfc 8.1.9 : Stall eh handlers if resetting while rport blocked · a90f5684
      由 James Smart 提交于 
      Stall error handler if attempting resets/aborts while an rport is blocked.
This avoids device offline scenarios due to errors in the error handler.

Background:
  Although the transport is using the scsi_timed_out functionality to
  restart the timeout if the rport is blocked, if the timeout has already
  fired before the block occurs, the eh handler still runs and can take
  the device offline. Ultimately, this window cannot be resolved without
  significant work in the error handler thread. Christoph noted the first
  level of these issues when he noted the poor error response handling
  by the error thread.

  We found, under heavy load and error testing, that time window from when
  the scsi_times_out() adds the io to the queue to when the scsi_error_handler
  gets around to servicing it, can be in the several seconds range. In most
  cases, these test conditions are highly unusual, but possible.
  As a result, we're stalling the error handler in this race window so that
  we can avoid the device_offline transitions.

      [SCSI] lpfc 8.1.9 : Misc Bug Fixes · 33ccf8d1
      由 James Smart 提交于 
      Misc Bug Fixes:
- Cap MBX_DOWN_LINK command timeout to 60 seconds
- Fix double free of ndlp object
- Don't free mbox structures on error. The completion handlers expect to do so.
- Clear host attention work items when going offline
- Fixed discovery issues in multi-initiator environments.

      [PATCH] fix compile regression for a few scsi drivers · 64821324
      由 Christoph Hellwig 提交于 
      This fixes three drivers to compile again after my patch that removes
the data_cmnd member from struct scsi_cmnd.

The fas216 change is trivial, it should have been using ->cmnd all the
time.

NCR53C9 (which seem to be mostly duplicate driver with esp.c!) is doing
something odd, it should only have looked at ->cmnd before not the saved
copy that is kept for the error handlers sake.  Note that it really
should deal with the sync setting themselves but use the generic domain
validation code that get this right - but that's for later let's push
this simple compile fix for now.

And sorry for the late fix for this, I have been busy with OLS and
associated activities last week.

      [PATCH] libata: improve EH action and EHI flag handling · 13abf50d
      由 Tejun Heo 提交于 
      Update ata_eh_about_to_do() and ata_eh_done() to improve EH action and
EHI flag handling.

* There are two types of EHI flags - one which expires on successful
  EH and the other which expires on a successful reset.  Make this
  distinction clear.

* Unlike other EH actions, reset actions are represented by two EH
  action masks and a EHI modifier.  Implement correct about_to_do/done
  semantics for resets.  That is, prior to reset, related EH info is
  sucked in from ehi and cleared, and after reset is complete, related
  EH info in ehc is cleared.

These changes improve consistency and remove unnecessary EH actions
caused by stale EH action masks and EHI flags.

      [PATCH] libata: fix eh_skip_recovery condition · 7c8c2cff
      由 Tejun Heo 提交于 
      * (ata_dev_absent() || ata_dev_ready()) test doesn't indicate
  SUSPENDED state properly.  Fix it.

* Link resuming resets shouldn't be skipped.  Don't skip recovery on
  EHI_RESUME_LINK.  This doesn't matter for host ports as EHI_RESUME
  always coincides with EHI_HOTPLUGGED which makes attached disabled
  devices vacant.  However, PMP reset causes non-hotplug link-resuming
  resets which shouldn't be skipped.

      [PATCH] libata: fix autopsy ehc->i.action and ehc->i.dev handling · 4528e4da
      由 Tejun Heo 提交于 
      Commit 0662c58b updated
ata_eh_autopsy() to OR determined action to ehc->i.action to preserve
action mask set directly into ehc->i.action by nested functions.  This
broke action mask clearing on SENSE_VALID case causing revalidation
and EH complete message on successful ATAPI CC.

This patch removes two local variables - action and failed_dev - which
cache ehc->i.action and ehc->i.dev respectively, and make the function
directly modify ehc->i.* fields to remove aliasing issues.
