scsi: remove eh_timed_out methods in the transport template

2017-02-07T00:10:03+00:00

Instead define the timeout behavior purely based on the host_template
eh_timed_out method and wire up the existing transport implementations
in the host templates.  This also clears up the confusion that the
transport template method overrides the host template one, so some
drivers have to re-override the transport template one.

ata: pass queued command to ->sff_data_xfer method

2017-01-10T16:11:17+00:00

For Atari Falcon PATA support we need to check the current command
in its ->sff_data_xfer method.  Update core code and all users
accordingly.

There should be no functional changes caused by this patch.

ata: ATA Command Priority Disabled By Default

2016-10-19T18:34:36+00:00

Add a sysfs entry to turn on priority information being passed
to a ATA device. By default this feature is turned off.

This patch depends on ata: Enabling ATA Command Priorities

tj: Renamed ncq_prio_on to ncq_prio_enable and removed trivial
    ata_ncq_prio_on() and open-coded the test.

ata: Enabling ATA Command Priorities

2016-10-19T18:34:36+00:00

This patch checks to see if an ATA device supports NCQ command priorities.
If so and the user has specified an iocontext that indicates
IO_PRIO_CLASS_RT then we build a tf with a high priority command.

This is done to improve the tail latency of commands that are high
priority by passing priority to the device.

tj: Removed trivial ata_ncq_prio_enabled() and open-coded the test.

libata: remove

2016-09-22T15:50:29+00:00

asm-generic is only intended for architecture defaults, and we can simply
kill it off by moving the two defintions directly to .

ata: define ATA_PROT_* in terms of ATA_PROT_FLAG_*

2016-07-19T00:55:38+00:00

This avoid the need to always translate between the two in ata_prot_flags
and generally cleans up the taskfile protocol usage.

Instead we can simply check for PIO or DMA in ata_is_data.

ata: Handle ATA NCQ NO-DATA commands correctly

2016-07-15T12:08:13+00:00

Add a new taskfile protocol ATA_PROT_NCQ_NODATA to handle
ATA NCQ NO-DATA commands correctly.
And fixup ata_scsi_zbc_out_xlat() to use it.
