Hi Javier, Samsung introduced Flexible Data Placement (FDP) technology pretty recently. As far as I know, currently, this technology is available for user-space solutions only. I assume it will be good to have discussion how kernel-space file systems could work with SSDs that support FDP technology by employing FDP benefits. How soon FDP API will be available for kernel-space file systems? How kernel-space file systems can adopt FDP technology? How FDP technology can improve efficiency and reliability of kernel-space file system? Which new challenges FDP technology introduces for kernel-space file systems? Could we have such discussion leading from Samsung side? Thanks, Slava
