Control of the enable/disable state of an ATA device Command Duration Limits (CDL) features has issues: 1) Incorrect feature state report translation in libata-scsi 2) The state reported when enabling the feature was being ignored, which caused needless SET FEATURES commands to be issued to the device, thus causing an unwanted reset of the CDL statistics log page (which is implied by any CDL activation action). These patches address these 2 issues. Martin, I can take the scsi patch if you are OK with it. Or the reverse, you can take all patches through the scsi tree if you prefer. Please let me know.
