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.
