Remove the conflict between fscontext and context mount options. If context= is specified without fscontext it will operate just as before, if both are specified we will use mount point labeling and all inodes will get the label specified by context=. The superblock will be labeled with the label of fscontext=, thus affecting operations which check the superblock security context, such as associate permissions.
