This lays the ground work for enabling casefolding and encryption at the same time for ext4 and f2fs. A future set of patches will enable that functionality. These unify the highly similar dentry_operations that ext4 and f2fs both use for casefolding. In addition, they improve d_hash by not requiring a new string allocation.
