chenrun1 dba77ff043 fslock:Optimize the performance overhead caused by frequent close 
Summary:
  Indicate whether the file is currently locked by adding a new field locked to filep.
    0 - Unlocked
    1 - Locked
  The status of the filep at close is used to determine whether to continue with the following procedure.

  Optimizing performance:
Before
  Time taken to close the file: 33984 nsec
After
  Time taken to close the file: 23744 nsec
Improvement of about 10 msec
