scsi_logging: return void for dev_printk() functions

2015-02-04T16:00:24Z

dev_printk() is now a void function, so the related functions scmd_printk() and sdev_prefix_printk() should be made void, too. Reported-by: Stephen Rothwell Signed-off-by: Hannes Reinecke Cc: Christoph Hellwig Signed-off-by: James Bottomley

scsi: Implement per-cpu logging buffer

2015-01-09T14:44:28Z

Implement a per-cpu buffer for formatting messages to avoid line breaks up under high load. This patch implements scmd_printk() and sdev_prefix_printk() using the per-cpu buffer and makes sdev_printk() a wrapper for sdev_prefix_printk().

SCSI / PM: Replace CONFIG_PM_RUNTIME with CONFIG_PM

2014-12-15T14:11:06Z

After commit b2b49ccbdd54 (PM: Kconfig: Set PM_RUNTIME if PM_SLEEP is selected) PM_RUNTIME is always set if PM is set, so #ifdef blocks depending on CONFIG_PM_RUNTIME may now be changed to depend on CONFIG_PM. Replace CONFIG_PM_RUNTIME with CONFIG_PM everywhere under drivers/scsi/ and in include/scsi/scsi_device.h. Signed-off-by: Rafael J. Wysocki Reviewed-by: Aaron Lu Acked-by: Christoph Hellwig

scsi: drop reason argument from ->change_queue_depth

2014-11-24T13:45:27Z

Drop the now unused reason argument from the ->change_queue_depth method. Also add a return value to scsi_adjust_queue_depth, and rename it to scsi_change_queue_depth now that it can be used as the default ->change_queue_depth implementation.

scsi: don't set tagging state from scsi_adjust_queue_depth

2014-11-12T10:19:43Z

Remove the tagged argument from scsi_adjust_queue_depth, and just let it handle the queue depth. For most drivers those two are fairly separate, given that most modern drivers don't care about the SCSI "tagged" status of a command at all, and many old drivers allow queuing of multiple untagged commands in the driver. Instead we start out with the ->simple_tags flag set before calling ->slave_configure, which is how all drivers actually looking at ->simple_tags except for one worke anyway. The one other case looks broken, but I've kept the behavior as-is for now. Except for that we only change ->simple_tags from the ->change_queue_type, and when rejecting a tag message in a single driver, so keeping this churn out of scsi_adjust_queue_depth is a clear win. Now that the usage of scsi_adjust_queue_depth is more obvious we can also remove all the trivial instances in ->slave_alloc or ->slave_configure that just set it to the cmd_per_lun default.
