scsi: dpt_i2o: Remove obsolete driver

2022-06-28T02:56:21+00:00

The dpt_i2o driver was fixed to stop using virt_to_bus() in 2008, but it still has a stale reference in an error handling code path that could never work. I submitted a patch to fix this reference earlier, but Hannes Reinecke suggested that removing the driver may be just as good here. The i2o driver layer was removed in 2015 with commit 4a72a7af462d ("staging: remove i2o subsystem"), but the even older dpt_i2o scsi driver stayed around. The last non-cleanup patches I could find were from Miquel van Smoorenburg and Mark Salyzyn back in 2008, they might know if there is any chance of the hardware still being used anywhere.

scsi: dpt_i2o: use scsi_host_complete_all_commands() to abort outstanding commands

2020-02-29T01:54:48+00:00

Rather than traversing all outstanding commands manually, use the scsi_host_complete_all_commands() helper to terminate all commands during reset. With that we can drop the cmd_list usage from the midlayer.

scsi: dpt_i2o: rename adpt_i2o_to_scsi() to adpt_i2o_scsi_complete()

2020-02-29T01:54:47+00:00

Rename the badly named function into adpt_i2o_scsi_complete(), and make it a void function as the return value is never used. This also fixes a potential use-after-free as the return value might be evaluated from the command result after the command has been freed.

dpt_i2o doesn't use scsi_register, so it should not use scsi_unregister either. Also refactor the module exit path to make a little more sense. Signed-off-by: Christoph Hellwig Signed-off-by: Martin K. Petersen

scsi: use 64-bit LUNs

2014-07-17T20:07:37+00:00

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.

SCSI host lock push-down

2010-11-16T21:33:23+00:00

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.
