2015-02-04	scsi_logging: return void for dev_printk() functions	Hannes Reinecke	1	-13/+9
	dev_printk() is now a void function, so the related functions scmd_printk() and sdev_prefix_printk() should be made void, too.

2015-01-09	scsi: use external buffer for command logging	Hannes Reinecke	1	-14/+168
	Use an external buffer for __scsi_print_command() and move command logging over to use the per-cpu logging buffer. With that we can guarantee the command always will always be formatted in one line. So we can even print out a variable length command correctly across several lines. Finally rename __scsi_print_command() to __scsi_format_comment() to better reflect the functionality.

2015-01-09	scsi: log request tag for scmd_printk()	Hannes Reinecke	1	-0/+4
	The request tag provides a concise identification of a SCSI command, so we should be printing that out for scmd_printk().

2015-01-09	scsi: Implement per-cpu logging buffer	Hannes Reinecke	1	-0/+124
	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().
