Oh, really sorry for this. 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:)
