[PATCH 02/15] fscrypt: clean up after fscrypt_prepare_lookup() conversions

Eric Biggers
2018-04-30T22:56:54Z

Now that all filesystems have been converted to use
fscrypt_prepare_lookup(), we can remove the fscrypt_set_d_op() and
fscrypt_set_encrypted_dentry() functions as well as un-export
fscrypt_d_ops.
