scsi: fusion: Fix error return code in mptfc_probe()

2016-09-14T18:26:19Z

Fix to return error code -ENOMEM from the workqueue alloc error handling case instead of 0, as done elsewhere in this function. Signed-off-by: Wei Yongjun Signed-off-by: Martin K. Petersen

scsi: mpt: Remove deprecated create_singlethread_workqueue

2016-09-02T10:13:57Z

The workqueues "ioc->reset_work_q" and "ioc->fw_event_q" queue a single work item &ioc->fault_reset_work and &fw_event->work, respectively and hence don't require ordering. Hence, they have been converted to use alloc_workqueue(). The WQ_MEM_RECLAIM flag has been set to ensure forward progress under memory pressure since the workqueue belongs to a storage driver which is being used on a memory reclaim path. Since there are fixed number of work items, explicit concurrency limit is unnecessary here. Signed-off-by: Bhaktipriya Shridhar Acked-by: Tejun Heo Signed-off-by: Martin K. Petersen

scsi: mptfc: Remove deprecated create_singlethread_workqueue

2016-09-02T10:12:01Z

The workqueue "fc_rescan_work_q" queues multiple work items viz &ioc->fc_rescan_work, &ioc->fc_lsc_work, &ioc->fc_setup_reset_work, which require strict execution ordering. Hence, an ordered dedicated workqueue has been used. WQ_MEM_RECLAIM has been set since the workqueue is belongs to a storage driver which is being used on a memory reclaim path and hence, requires forward progress under memory pressure.

scsi: disable automatic target scan

2016-04-11T20:57:09Z

On larger installations it is useful to disable automatic LUN scanning, and only add the required LUNs via udev rules. This can speed up bootup dramatically. This patch introduces a new scan module parameter value 'manual', which works like 'none', but can be overridden by setting the 'rescan' value from scsi_scan_target to 'SCSI_SCAN_MANUAL'. And it updates all relevant callers to set the 'rescan' value to 'SCSI_SCAN_MANUAL' if invoked via the 'scan' option in sysfs. Signed-off-by: Hannes Reinecke Reviewed-by: Ewan D.
