    JFS: Better RAS when btstack is overrun · fa2c79c3
    Dave Kleikamp authored
    The current warning and/or trap when the btstack is overrun in
    dtSearch or dtReadFirst are not very helpful.  Add code to detect
    the stack overrun earlier, print something useful, and return
    gracefully.
    
    I've found that dbFree being called with blkno == 0 can lead to this
    error, so I put in a specific check for that.
