From: Marc Carino <marc.ceeeee@xxxxxxxxx> This patch series updates the libata driver with some additional commands which are specified in the more recent versions of the SATA and ATA specifications. These commands are: SEND FPDMA QUEUED RECEIVE FPDMA QUEUED. The new queued commands augment the existing READ and WRITE FPDMA QUEUED commands. The commands are intended to transport non-media data to/from a device in a non-blocking manner. One application of these commands include a queued-style DSM TRIM operation. The current DSM TRIM command is non-queued, and requires the initiator to empty out the queue before issuance. The new DSM TRIM allows the host to keep the queue full. These patches have been validated on an Intel SATA AHCI controller, on a Micron M500 SSD, using "postmark," "fstrim," and "fsck."
