  "message": "[SCSI] libsas: support NCQ for SATA disks\n\nThis patch adds SATAII NCQ support to libsas.  Both the use_ncq and the\ndma_xfer flags in ata_task must be set for NCQ to work correctly on the\nAdaptec SAS controller.  The rest of the patch adds ATA_FLAG_NCQ to\nsata_port_info and sets up ap-\u003escsi_host so that ata_setup_ncq doesn\u0027t\ncrash.  Please note that this patch is against the aic94xx-sas git tree,\nnot scsi-misc.  Thanks also to James Bottomley for providing an earlier\nversion of this patch from which to work.\n\nI\u0027ve tested this patch on a x206m with a ST380819AS SATA2 disk plugged\ninto the Adaptec SAS controller.  The drive came up with a queue depth\nof 31, and I successfully ran an I/O flood test to coerce libata into\nsending multiple commands simultaneously.  A kernel probe recorded the\nmaximum tag number that had been seen before and after the flood test;\nbefore the test it was 2 and after it was 30, as I expected.\n\nSigned-off-by: Darrick J.
