    sys/kern             kern_descrip.c kern_fork.c 
  Log:
  MFC: Avoid file lock leakage when linuxthreads port or rfork is used:
         - Mark the process leader as having an advisory lock
         - Check if process leader is marked as having advisory lock when
           closing file
         - Check that file is still open after lock has been obtained
         - Don't allow file descriptor table sharing between processes
           with different leaders
