      scsi: mpt3sas: Avoid sleeping in interrupt context · 8893cf6c
      由 Bart Van Assche 提交于 
      Commit 669f0441 ("scsi: srp_transport: Move queuecommand() wait code
to SCSI core") can make scsi_internal_device_block() sleep.  However,
the mpt3sas driver can call this function from an interrupt
handler. Hence add a second argument to scsi_internal_device_block()
that restores the old behavior of this function for the mpt3sas handler.

The call chain that triggered an "IRQ handler enabled interrupts"
complaint is as follows:

_base_interrupt()
-> _base_async_event()
   -> mpt3sas_scsih_event_callback()
      -> _scsih_check_topo_delete_events()
         -> _scsih_block_io_to_children_attached_directly()
            -> _scsih_block_io_device()
               -> _scsih_internal_device_block()
                  -> scsi_internal_device_block()

      scsi: sd: Check for unaligned partial completion · c46f0917
      由 Damien Le Moal 提交于 
      Commit <f2e767bb> ("mpt3sas: Force request partial completion
alignment") was not considering the case of commands not operating on
logical block size units (e.g. REQ_OP_ZONE_REPORT and its 64B aligned
partial replies). In this case, forcing alignment of resid to the device
logical block size can break the command result, e.g. in the case of
REQ_OP_ZONE_REPORT, the exact number of zone reported by the device.

Move the partial completion alignement check of mpt3sas to a generic
implementation in sd_done(). The check is added within the default
section of the initial req_op() switch case so that the report and reset
zone commands are ignored. In addition, as sd_done() is not called for
passthrough requests, resid corrections are not done as intended by the
initial mpt3sas patch.

      scsi: mpt3sas: Fix secure erase premature termination · 18f6084a
      由 Andrey Grodzovsky 提交于 
      This is a work around for a bug with LSI Fusion MPT SAS2 when perfoming
secure erase. Due to the very long time the operation takes, commands
issued during the erase will time out and will trigger execution of the
abort hook. Even though the abort hook is called for the specific
command which timed out, this leads to entire device halt
(scsi_state terminated) and premature termination of the secure erase.

Set device state to busy while ATA passthrough commands are in progress.

      scsi: mpt3sas: Fix for block device of raid exists even after deleting raid disk · 6d3a56ed
      由 Sreekanth Reddy 提交于 
      While merging mpt3sas & mpt2sas code, we added the is_warpdrive check
condition on the wrong line

---------------------------------------------------------------------------
 scsih_target_alloc(struct scsi_target *starget)
                        sas_target_priv_data->handle = raid_device->handle;
                        sas_target_priv_data->sas_address = raid_device->wwid;
                        sas_target_priv_data->flags |= MPT_TARGET_FLAGS_VOLUME;
-                       raid_device->starget = starget;
+                       sas_target_priv_data->raid_device = raid_device;
+                       if (ioc->is_warpdrive)
+                               raid_device->starget = starget;
                }
                spin_unlock_irqrestore(&ioc->raid_device_lock, flags);
                return 0;
------------------------------------------------------------------------------

That check should be for the line sas_target_priv_data->raid_device =
raid_device;

Due to above hunk, we are not initializing raid_device's starget for
raid volumes, and so during raid disk deletion driver is not calling
scsi_remove_target() API as driver observes starget field of
raid_device's structure as NULL.
