This is the diff to the original OpenSuSE 12.2 kernel: itms2:/lib/modules/3.4.11-2.16-desktop/source/fs/cifs # diff readdir_orig.c readdir.c 78a79

if (inode) { /* * If we're generating inode numbers, then we don't * want to clobber the existing one with the one that * the readdir code created. */ if (!(cifs_sb->mnt_cifs_flags & CIFS_MOUNT_SERVER_INUM)) fattr->cf_uniqueid = CIFS_I(inode)->uniqueid;
