  SVN rev 194693 on 2009-06-23 10:47:42Z by kib
  
  MFC r192683:
  In lf_advlockasync(), recheck for doomed vnode after the state->ls_lock
  is acquired. In the lf_purgelocks(), assert that vnode is doomed and set
  *statep to NULL before clearing ls_pending list. Otherwise, we allow for
  the thread executing lf_advlockasync() to put new pending entry after
  state->ls_lock is dropped in lf_purgelocks().
  
  MFC r193931:
  Do not leak the state->ls_lock after VI_DOOMED check introduced
  in the r192683.
  
  MFC r194356:
  Decrement state->ls_threads when vnode appeared to be doomed.
