fs/reiserfs/buffer2.c, line ~28:
atomic_t gets the const quality on account of being a member
of a const struct buffer_head instance.

void wait_buffer_until_released (const struct buffer_head * bh)
{
  int repeat_counter = 0;

  while (atomic_read (&(bh->b_count)) > 1) {

    if ( !(++repeat_counter % 30000000) ) {
      reiserfs_warning ("vs-3050: wait_buffer_until_released: nobody releases buffer (%b). Still waiting (%d) %cJDIRTY %cJWAIT\n",
			bh, repeat_counter, buffer_journaled(bh) ? ' ' : '!',
			buffer_journal_dirty(bh) ? ' ' : '!');
    }
    run_task_queue(&tq_disk);
    yield();
  }
  if (repeat_counter > 30000000) {
    reiserfs_warning("vs-3051: done waiting, ignore vs-3050 messages for (%b)\n", bh) ;
  }
}
