At fs/jffs2/gc.c,v 1.52, line 460:

        fill:
                ri.magic = JFFS2_MAGIC_BITMASK;
                ri.nodetype = JFFS2_NODETYPE_INODE;
                ri.totlen = sizeof(ri);
                ri.hdr_crc = crc32(0, &ri, sizeof(struct
jffs2_unknown_node)-4);
 
                ri.ino = inode->i_ino;
                ri.version = ++f->highest_version;
                ri.offset = start;
                ri.csize = end - start;
                ri.dsize = 0;
                ri.compr = JFFS2_COMPR_ZERO;

This seems backwards to me.  Shouldn't ri.dsize = end-start and ri.csize
= 0 ???
