  Modified files:
    sys/sys              rwlock.h 
    sys/kern             kern_rwlock.c 
  Log:
  Add rw_wowned() interface to rwlock(9), allowing a kernel thread to
  determine if it holds an exclusive rwlock reference or not.  This is
  non-ideal, but recursion scenarios in the network stack currently
  require it.
