fscrypt: allow deleting files with unsupported encryption policy (2020-12-02 18:25:01 -0800)

----------------------------------------------------------------

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.

----------------------------------------------------------------
