Subject: [PATCH v12 0/4] Prepare for upcoming Casefolding/Encryption patches

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.

Daniel Rosenberg (4):
  unicode: Add utf8_casefold_hash
  fs: Add standard casefolding support
  f2fs: Use generic casefolding support
  ext4: Use generic casefolding support
