copy_file_range calls do_splice_direct() if fs->clone_file_range or fs->copy_file_range() is not available. However, do_splice_direct() converts holes to zeros. Detect holes in the file_in range, and create them in the corresponding file_out range.
Should this be restricted to calls to copy_file_range with a (yet-to-be-defined) flag?
I was under the impression that the hole-filling nature of copy_file_range was not a bug.
