ceph: use default file splice read callback
Splice read/write implementation changed recently. When using generic_file_splice_read(), iov_iter with type == ITER_PIPE is passed to filesystem's read_iter callback. But ceph_sync_read() can't serve ITER_PIPE iov_iter correctly (ITER_PIPE iov_iter expects pages from page cache). Fixing ceph_sync_read() requires a big patch. So use default splice read callback for now. Signed-off-by: Yan, Zheng <zyan@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
