I forgot to check the linux-next git. I'm not sure if commit 9bf93dcfc453 will lead to sb refcount leak which was previously fixed by ac2c63757f4f ("orangefs: Fix sb refcount leak when allocate sb info failed."). In any case, the null pointer problem has been solved. Thanks for your reminder:) Su Hui
