The check for a null inode is redundant since the function is a callback for exportfs, which will itself crash if dentry->d_inode or parent->d_inode is NULL. Removing the null check makes this consistent with other file systems. Also remove the redundant null dir check too. Found with static analysis by CoverityScan, CID 1389472 Kudos to Jeff Mahoney for reviewing and explaining the error in my original patch (most of this explanation went into the above commit message) and David Sterba for pointing out that the dir check is also redundant.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
