    sys/kern             kern_lockf.c 
  Log:
  Fix three bugs in the last commit and document special cases.  Tighten
  up the count calculation.   The code now passes the /usr/src/test/lockf
  system test.
  
  * F_UNLCK wasn't being handled properly in certain cases, resulting in a
    panic.
  
  * The 'next' pointer was not bring properly adjusted when removing an
    element (brange) other then the current element in the scan, resulting
    in a posix lock error.
  
  * The first and last matches were not always being properly merged with
    the created range, resulting in a positive count panic.
