Hi all, I was wondering if anyone had any insights as to the status of http://tracker.ceph.com/projects/ceph/wiki/Zero-copy_bufferlists? Poking around in the buffer code I see that there is some code there to handle zero copy with buffer::raw, but that it's disabled (the if (false && read_fd_zero_copy(fd, len) == 0) in buffer::list::read_fd), and that the read path for osd's using FileStore doesn't appear to go through buffer anyway (FileStore::read uses safe_pread) Was this direction determined to not be worth it, or is it just that no one has had the time to keep pursuing it? thanks, -emile ��.n��������+%������w��{.n����z��u���ܨ}���Ơz�j:+v�����w����ޙ��&�)ߡ�a����z�ޗ���ݢj��w�f
