Subject: [PATCH 5.4 0/4] fscrypt: prevent creating duplicate encrypted filenames

Backport four commits from v5.11-rc1.  I resolved a conflict in the
first one.  The rest are clean cherry-picks which didn't get picked up
yet because they depend on the first one.

Eric Biggers (4):
  fscrypt: add fscrypt_is_nokey_name()
  ext4: prevent creating duplicate encrypted filenames
  f2fs: prevent creating duplicate encrypted filenames
  ubifs: prevent creating duplicate encrypted filenames
