More importantly these constant have been around forever, so we'd better have a really good argument for changing them.
Hi Christoph, I will drop this patch. As you know the NVMe and SCSI specifications use the numeric range 0..63 for the data lifetime so there is a gap between the values supported by the F_[GS]ET_RW_HINT fcntls and the data lifetime values accepted by widely used storage devices. Do you think that it should be possible for user space applications to specify the full range (0..63)? Thanks, Bart.
