mount_crypt_stat is assigned to &ecryptfs_superblock_to_private(ecryptfs_dentry->d_sb)->mount_crypt_stat, and mount_crypt_stat is not the first object in struct ecryptfs_sb_info. mount_crypt_stat is therefore never NULL. At the same time, no crash in ecryptfs_lookup() has been reported, and the lookup functions in other file systems don't check if d_sb is NULL either. Given that, remove the NULL check.

README
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.
