    kernel - devfs - Fix deadlocks
    
    * Fix a deadlocks when the core thread attempts to free a node.  The
      devfs lock must be released when obtaining the vnode lock.  Fixes
      issues with ls -la /dev/pts when running stress2{pts}.
    
    * Adjust devfs_config() to not attempt to message the devfs core thread
      if the core thread has terminated (fixes issues with reboot).
