random: wire up fops->splice_{read,write}_iter()
Now that random/urandom is using {read,write}_iter, we can wire it up to using the generic splice handlers. Fixes: 36e2c7421f02 ("fs: don't allow splice read/write without explicit ops") Signed-off-by: Jens Axboe <axboe@kernel.dk> [Jason: added the splice_write path. Note that sendfile() and such still does not work for read, though it does for write, because of a file type restriction in splice_direct_to_actor(), which I'll address separately.] Cc: Al Viro <viro@zeniv.linux.org.uk> Signed-off-by: Jason A. Donenfeld <Jason@zx2c4.com>
