- max_data = (asoc->pathmtu - - sctp_sk(asoc->base.sk)->pf->af->net_header_len - - sizeof(struct sctphdr) - sizeof(struct sctp_data_chunk)) & ~3; + max_data = asoc->pathmtu - + sctp_sk(asoc->base.sk)->pf->af->net_header_len - + sizeof(struct sctphdr) - sizeof(struct sctp_data_chunk); + max_data = WORD_TRUNC(max_data);
Hmmm.... Am I the only person who understands immediately what & ~3 does but would have to grovel through the headers to find exactly what WORD_TRUNC() does. How big is a 'WORD' anyway?? David
