  Log:
  Eliminate VI_LOCK()/VI_UNLOCK() pair from getattr and close code paths.
  It's hard to measure performance improvement on my test machine, but the
  change won't degrade performance for sure. I can measure slight improvement
  for debugging kernel and it can also be a win for machines where atomic
  operation is more expensive.
