kernfs: wire up ->splice_read and ->splice_write
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. Fixes: 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") Reported-by: Siddharth Gupta <sidgup@codeaurora.org> Tested-by: Siddharth Gupta <sidgup@codeaurora.org> Signed-off-by: Christoph Hellwig <hch@lst.de> Link: https://lore.kernel.org/r/20210120204631.274206-4-hch@lst.de Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
