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.
