Subject: Problem with debugfs

Hi, there,

I do not know who is the maintainer for debugfs now. But I think there is
problem with its API: It uses filp->priv->mutex to protect the read/write (to
the file) for the value of its attribute, but the mutex is not exported to the
API user.  Therefore, there is no way to protect its value when you directly
use the value in your module.

Is my understanding correct?

Thanks

Best Regards
Kenneth Lee
