Parent article: copy_range()

I'm trying to understand why the in_offset and out_offset parameters need to be pointers. At first I assumed it was to correct for non block-aligned offsets. However, the prototype for vfs_copy_range drops them [1]. Perhaps I missed something on first glance..

vfs_copy_range(struct file *file_in, loff_t pos_in,
struct file *file_out, loff_t pos_out,
size_t count)
