From: Christoph Hellwig <hch@lst.de>
commit f2d6c2708bd84ca953fa6b6ca5717e79eb0140c7 upstream.
Wire up the splice_read and splice_write methods to the default helpers using ->read_iter and ->write_iter now that those are implemented for kernfs. This restores support to use splice and sendfile on kernfs files.
