Thanks for the feedback. We have taken care of these. There are two follow-ups to do. 1. moving whole or part of drivers/ata/ahci.h to include/linux 2. mtip32xx support 32-bit ioctls too. For now, we have defined compat equivalent of struct ide_task_request_s locally. We need this support in hdreg.h -- Regards, Asai Thambi
