From: Damien Le Moal <damien.lemoal@xxxxxxxxxxxxxxxxxx> Introduce the command duration limits helper function sd_cdl_dld() to set the DLD bits of READ/WRITE 16 and READ/WRITE 32 commands to indicate to the device the command duration limit descriptor to apply to the commands. When command duration limits are enabled, sd_cdl_dld() obtains the index of the descriptor to apply to the command using the hints field of the request IO priority value (hints IOPRIO_HINT_DEV_DURATION_LIMIT_1 to IOPRIO_HINT_DEV_DURATION_LIMIT_7). If command duration limits is disabled (which is the default), the limit index "0" is always used to indicate "no limit" for a command.
