scsi: remove eh_timed_out methods in the transport template

2017-02-07T00:10:03Z

Instead define the timeout behavior purely based on the host_template eh_timed_out method and wire up the existing transport implementations in the host templates. This also clears up the confusion that the transport template method overrides the host template one, so some drivers have to re-override the transport template one.

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: use 64-bit LUNs

2014-07-17T20:07:37Z

The SCSI standard defines 64-bit values for LUNs, and large arrays employing large or hierarchical LUN numbers become more and more common. So update the linux SCSI stack to use 64-bit LUN numbers.

Drivers: message: remove __dev* attributes.

2013-01-03T23:57:14Z

CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

SCSI host lock push-down

2010-11-16T21:33:23Z

Move the mid-layer's ->queuecommand() invocation from being locked with the host lock to being unlocked to facilitate speeding up the critical path for drivers who don't need this lock taken anyway. The patch below presents a simple SCSI host lock push-down as an equivalent transformation. No locking or other behavior should change with this patch. All existing bugs and locking orders are preserved. Additionally, add one parameter to queuecommand, struct Scsi_Host * and remove one parameter from queuecommand, void (*done)(struct scsi_cmnd *) Scsi_Host* is a convenient pointer that most host drivers need anyway, and 'done' is redundant to struct scsi_cmnd->scsi_done. Minimal code disturbance was attempted with this change. Most drivers needed only two one-line modifications for their host lock push-down.
