* scsi_logging: return void for dev_printk() functionsHannes Reinecke2015-02-041-13/+9
| | | | | | | | | | dev_printk() is now a void function, so the related functions scmd_printk() and sdev_prefix_printk() should be made void, too.

* scsi: use external buffer for command loggingHannes Reinecke2015-01-091-14/+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.

* scsi: log request tag for scmd_printk()Hannes Reinecke2015-01-091-0/+4
| | | | | | | | | | | The request tag provides a concise identification of a SCSI command, so we should be printing that out for scmd_printk().

* scsi: Implement per-cpu logging bufferHannes Reinecke2015-01-091-0/+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().
