Spotted while hunting http://tracker.ceph.com/issues/10905. >From struct ceph_msg_data_cursor in include/linux/ceph/messenger.h: bool last_piece; /* current is last piece */ In ceph_msg_data_next(): *last_piece = cursor->last_piece; A call to ceph_msg_data_next() is followed by: ret = ceph_tcp_sendpage(con->sock, page, page_offset, length, last_piece); while ceph_tcp_sendpage() is: static int ceph_tcp_sendpage(struct socket *sock, struct page *page,i int offset, size_t size, bool more) The logic is inverted: correct it.
