[PATCHv2 00/68] libata: rework logging, take II

[Hannes Reinecke]

Hi all,

after some prodding from individual persons I've resurrected my
patchset to put libata logging on a even keel, and use structured
logging for everything.
So this patch does away with DPRINTK, ATA_DEBUG or ata_msg_XXX()
calls, and moves everything over to structured logging
(ie the dev_XXX() calls).
Additionally I've added tracepoints to trace command flow,
error handling, host state machine etc.

So everything is looking far saner now.

As usual, comments and reviews are welcome.

I know that the device names suck. Blame Tejun.

Changes to the original submission:
- Converted all printk() and pr_XXX() calls, too
- Included reviews from Damien
- Included reviews from Sergey

[PATCH 01/68] libata: remove pointless debugging messages

[Hannes Reinecke]

Debugging messages in pci init functions or sg setup are pretty
much pointless, as the workflow pretty much decides what happened.
So drop them.

[PATCH 03/68] libata: Add ata_port_classify() helper

[Hannes Reinecke]

Add an ata_port_classify() helper to print out the results from
the device classification and remove the debugging statements
from ata_dev_classify().

[PATCH 04/68] libata: move ata_dump_id() to dynamic debugging

[Hannes Reinecke]

Use ata_dev_dbg() to print out the information in ata_dump_id()
and remove the ata_msg_probe() conditional.

[PATCH 05/68] libata: sanitize ATA_HORKAGE_DUMP_ID

[Hannes Reinecke]

With moving ata_dev_dbg() over to dynamic debugging ATA_HORKAGE_DUMP_ID
will now print out the raw IDENTIFY data without a header unless
explicitly enable via dyndebug.
So move the logging level up to INFO and have the header printed
always.

[PATCH 06/68] libata: add reset tracepoints

[Hannes Reinecke]

To follow the flow of control we should be using tracepoints, as
they will tie in with the actual I/O flow and deliver a better
overview about what it happening.
This patch adds tracepoints for hard reset, soft reset, and postreset
and adds them in the libata-eh control flow.
With that we can drop the reset DPRINTK calls in the various drivers.

[PATCH 07/68] libata: add qc_prep tracepoint

[Hannes Reinecke]

Convert the existing ata_qc_issue() tracepoint into a template,
and add tracepoints for ata_qc_prep() and ata_qc_issue() based
on that template.

[PATCH 10/68] libata-scsi: drop DPRINTK calls for cdb translation

[Hannes Reinecke]

Drop DPRINTK calls for cdb translation as they are already covered
by other traces, and also drop the DPRINTK calls in ata_scsi_hotplug().

[PATCH 22/68] pata_pdc2027x: Replace PDPRINTK() with standard ata logging

[Hannes Reinecke]

From: Hannes Reinecke <hare@suse.com>

Use standard ata logging macros instead of the hand-crafted
PDPRINTK and remove duplicate logging messages.

[PATCH 23/68] libata: remove pointless VPRINTK() calls

[Hannes Reinecke]

Most of the information is already covered by tracepoints
(if not downright pointless), so remove the VPRINTK() calls.
And while we're at it, remove ata_scsi_dump_cdb(), too,
as this information can be retrieved from scsi tracing.

[PATCH 65/68] libata-scsi: rework ata_dump_status to avoid using pr_cont()

[Hannes Reinecke]

pr_cont() has the problem that individual calls will be disrupted
under high load, causing each call to end up on a single line and
thereby mangling the output.
So rework ata_dump_status() to have just one call to ata_port_warn()
and avoid this problem.
