      The __rec_split_write function is defined as shown below:

      static int
__rec_split_write(WT_SESSION_IMPL *session, WT_RECONCILE *r, WT_REC_CHUNK *chunk,
  WT_ITEM *compressed_image, bool last_block)
{

      The compressed_image arg seems to always be NULL in our code:

      src/reconcile/rec_write.c:1511:        WT_RET(__rec_split_write(session, r, r->cur_ptr, NULL, false));
src/reconcile/rec_write.c:1514:            WT_RET(__rec_split_write(session, r, r->prev_ptr, NULL, false));
src/reconcile/rec_write.c:1715:    return (__rec_split_write(session, r, r->prev_ptr, NULL, false));
src/reconcile/rec_write.c:1768:            WT_RET(__rec_split_write(session, r, r->prev_ptr, NULL, false));
src/reconcile/rec_write.c:1772:    return (__rec_split_write(session, r, r->cur_ptr, NULL, true));

      I am wondering if this a bug or just dead code.
