|/ | | | | | | | | | | | | | | | | | | | | Commit 141f3d6256e5 ("ata: libata-sata: Fix device queue depth control") added a struct ata_device argument to ata_change_queue_depth() to address problems with changing the queue depth of ATA devices managed through libsas. This was due to problems with ata_scsi_find_dev() which are now fixed with commit 7f875850f20a ("ata: libata-scsi: Use correct device no in ata_find_dev()"). Undo some of the changes of commit 141f3d6256e5: remove the added struct ata_device aregument and use again ata_scsi_find_dev() to find the target ATA device structure. While doing this, also make sure that ata_scsi_find_dev() is called with ap->lock held, as it should. libsas and libata call sites of ata_change_queue_depth() are updated to match the modified function arguments.

| | | | | | | | | | | | | | | | | | | | | 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.

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->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->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->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.

|/ | | | | | | | | | | | | | | | | | | | The function __ata_change_queue_depth() uses the helper ata_scsi_find_dev() to get the ata_device structure of a scsi device and set that device maximum queue depth. However, when the ata device is managed by libsas, ata_scsi_find_dev() returns NULL, turning __ata_change_queue_depth() into a nop, which prevents the user from setting the maximum queue depth of ATA devices used with libsas based HBAs. Fix this by renaming __ata_change_queue_depth() to ata_change_queue_depth() and adding a pointer to the ata_device structure of the target device as argument. This pointer is provided by ata_scsi_change_queue_depth() using ata_scsi_find_dev() in the case of a libata managed device and by sas_change_queue_depth() using sas_to_ata_dev() in the case of a libsas managed ata device.
