- * This is a little more tricky than the file -> pipe splicing. There are
- * basically three cases:
- *
- *	- Destination page already exists in the address space and there
- *	  are users of it. For that case we have no other option that
- *	  copying the data. Tough luck.
- *	- Destination page already exists in the address space, but there
- *	  are no users of it. Make sure it's uptodate, then drop it. Fall
- *	  through to last case.
- *	- Destination page does not exist, we can add the pipe page to
- *	  the page cache and avoid the copy.
- *
- * If asked to move pages to the output file (SPLICE_F_MOVE is set in
- * sd->flags), we attempt to migrate pages from the pipe to the output
- * file address space page cache. This is possible if no one else has
- * the pipe page referenced outside of the pipe and page cache. If
- * SPLICE_F_MOVE isn't set, or we cannot move the page, we simply create
- * a new page in the output file page cache and fill/dirty that.
