Enable will Records the number of filep references. The file is
actually closed when the count reaches 0

Note that this option will ensure the safety of access to the file
system from multi-tasks (thread A blocking rw(fd), then thread B close(fd)),
the disadvantage is that it will increase the amount of code-size,
there is no need to enable this option if the application could ensure
he file operations are safe.
