<content type='text'>
When a disk is removed with in-flight I/O, the application needs to wait
for 30 seconds (depending on the timeout configuration) to hear back from
the kernel. Xingui tried to fix this issue by aborting the ATA link for
SATA devices[1], however this approach left the SAS devices unresolved.

Try to fix this issue by aborting all in-flight requests when the device is
gone. This is implemented by iterating over the tagset.

Pull ATA updates from Damien Le Moal:

 - Small cleanup of the pata_octeon driver to drop a useless platform
   callback (Uwe)

 - Simplify ata_scsi_cmd_error_handler() code using the fact that
   ap-&gt;ops-&gt;error_handler is NULL most of the time (Wenchao)

 - Several patches improving libata error handling. This is in
   preparation for supporting the command duration limits (CDL) feature.
   The changes allow handling corner cases of ATA NCQ errors which do
   not happen with regular drives but will be triggered with CDL drives
   (Niklas)

 - Simplify the qc_fill_rtf operation (me)

 - Improve SCSI command translation for REPORT_SUPPORTED_OPERATION_CODES
   command (me)

 - Cleanup of libata FUA handling.

   This falls short of enabling FUA for ATA drives that support it by
   default as there were concerns that old drives would break. The
   series however fixes several issues with the FUA support to ensure
   that FUA is reported as being supported only for drives that can
   handle all possible write cases (NCQ and non-NCQ). A check in the
   block layer is also added to ensure that we never see read FUA
   commands (current behavior) (me)

 - Several patches to move the old PARIDE (parallel port IDE) driver to
   libata as pata_parport. Given that this driver also needs protocol
   modules, the driver code resides in its own pata_parport directoy
   under drivers/ata (Ondrej)

The boolean return value of the qc_fill_rtf operation is used nowhere.
Simplify this operation interface by making it a void function. All
drivers defining this operation are also updated.

<title>ata: scsi: rename flag ATA_QCFLAG_FAILED to ATA_QCFLAG_EH</title>

<id>urn:sha1:876293121f24fc1a7df85450d0997f54540c8979</id>
<content type='text'>
The name ATA_QCFLAG_FAILED is misleading since it does not mean that a
QC completed in error, or that it didn't complete at all. It means that
libata decided to schedule EH for the QC, so the QC is now owned by the
libata error handler (EH).

The normal execution path is responsible for not accessing a QC owned
by EH. libata core enforces the rule by returning NULL from
ata_qc_from_tag() for QCs owned by EH.

It is quite easy to mistake that a QC marked with ATA_QCFLAG_FAILED was
an error. However, a QC that was actually an error is instead indicated
by having qc-&gt;err_mask set. E.g. when we have a NCQ error, we abort all
QCs, which currently will mark all QCs as ATA_QCFLAG_FAILED. However, it
will only be a single QC that is an error (i.e. has qc-&gt;err_mask set).

Rename ATA_QCFLAG_FAILED to ATA_QCFLAG_EH to more clearly highlight that
this flag simply means that a QC is now owned by EH. This new name will
not mislead to think that the QC was an error (which is instead
indicated by having qc-&gt;err_mask set).

This also makes it more obvious that the EH code skips all QCs that do
not have ATA_QCFLAG_EH set (rather than ATA_QCFLAG_FAILED), since the EH
code should simply only care about QCs that are owned by EH itself.

unify the error handling.

Factor out sas_ata_add_dev() and put it in sas_ata.c since it is a SATA
related interface. Also follow the standard coding style to define an
inline empty function when CONFIG_SCSI_SAS_ATA is not enabled.
