scsi: mpt3sas: Fix for block device of raid exists even after deleting raid disk
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.
