  Modified files:
    sys/ufs/ufs          ufs_vnops.c 
  Log:
  Fixed null pointer panics which I introduced in rev.1.86.  Vnodes
  may be revoked, so vnop routines must be careful about accessing
  the vnode if they may have blocked.
  
  Fixed marking for update after successfully reading or writing 0
  bytes.  In this case, POSIX.1 specifies marking if and only if the
  requested count is nonzero, but rev.1.86 never marked.
