Did you test this? Is this really a reference count when looking at the
code? Or is it just a counter that we use for dealing with vfs issues?
Usually filesystems and the vfs can not use the refcount_t type for
various reasons, please do some research on that before making these
And of course, please explain how you tested this patch if you resubmit
it with the needed information.
