  Modified files:
    sys/kern             kern_descrip.c 
  Log:
   - Use explicit locking in the various fcntl case statements so that we
     can acquire shared filedescriptor locks in the appropriate cases.
   - Remove Giant from calls that issue ioctls.  The ioctl path has been
     mpsafe for some time now.
   - Only acquire giant for VOP_ADVLOCK when the filesystem requires giant.
     advlock is now mpsafe.
