Subject: [PATCH 0/4] fscrypt: make '-o test_dummy_encryption' support v2 policies

v1 encryption policies are deprecated in favor of v2, and some new
features (e.g. encryption+casefolding) are only being added for v2.

As a result, the "test_dummy_encryption" mount option (which is used for
encryption I/O testing with xfstests) needs to support v2 policies.

Therefore, this patchset adds support for specifying
"test_dummy_encryption=v2" (or "test_dummy_encryption=v1").
To make this possible, it reworks the way the test_dummy_encryption
mount option is handled to make it more flexible than a flag, and to
automatically add the test dummy key to the filesystem's keyring.

Patch 4 additionally changes the default to "v2".

This patchset applies to v5.7-rc4.

Eric Biggers (4):
  linux/parser.h: add include guards
  fscrypt: add fscrypt_add_test_dummy_key()
  fscrypt: support test_dummy_encryption=v2
  fscrypt: make test_dummy_encryption use v2 by default
