[PATCHv2 00/20] scsi logging update

Hi all,

here's the second version of my scsi logging updates.
Main feature is the update to have all logging
statements in one line so that they won't be broken
up even under high load.
This will dramatically improve debugging.

Additionally all printk() statements are moved
to dev_printk() variants to ensure proper device
tagging and keep the systemd journal happy.

To achieve this I had to use a on-stack
buffer for formatting opcodes and sense codes;
so the stack usage will increase somewhat.

This is the second iteration; in this I've included
the reviews from Christoph Hellwig and Robert Elliot.

Reviews, comments etc are welcome.

Hannes Reinecke (20):
Remove scsi_cmd_print_sense_hdr()
aha152x: Debug output update and whitespace cleanup
sd: Remove scsi_print_sense() in sd_done()
scsi: introduce sdev_prefix_printk()
scsi: Use sdev as argument for sense code printing
scsi: stop decoding if scsi_normalize_sense() fails
scsi: do not decode sense extras
scsi: use 'bool' as return value for scsi_normalize_sense()
scsi: remove scsi_print_status()
Implement scsi_opcode_sa_name
scsi: Use scsi_print_command() where possible
scsi: merge print_opcode_name()
scsi: consolidate opcode lookup in scsi_opcode_sa_name()
scsi: use local buffer for printing CDB
libata: use __scsi_print_command()
scsi: separate out scsi_retval_string()
scsi: separate out scsi_host_hostbyte() and scsi_show_driverbyte()
scsi: remove scsi_show_result()
sd: Reduce logging output
scsi_error: format abort error message
