Merge tag 'fscrypt-for-linus' of git://git./fs/fscrypt/fscrypt

Pull fscrypt updates from Eric Biggers:
 "This release there are some fixes for longstanding problems, as well
  as some cleanups:

   - Fix a race condition where a duplicate filename could be created in
     an encrypted directory if a syscall that creates a new filename
     raced with the directory's encryption key being added.

   - Allow deleting files that use an unsupported encryption policy.

   - Simplify the locking for 'struct fscrypt_master_key'.

   - Remove kernel-internal constants from the UAPI header.

  As usual, all these patches have been in linux-next with no reported
  issues, and I've tested them with xfstests"
