[PATCH v2 01/11] fscrypt: move fscrypt_has_encryption_key() to supp/notsupp headers

[Eric Biggers]

From: Eric Biggers <ebiggers at google.com>

fscrypt_has_encryption_key() is already split into two versions
depending on whether the filesystem is being built with encryption
support or not.  Move them into the appropriate headers.
