fscrypt: move fscrypt_is_dot_dotdot() to fs/crypto/fname.c
Only fs/crypto/fname.c cares about treating the "." and ".." filenames specially with regards to encryption, so move fscrypt_is_dot_dotdot() from fscrypt.h to there. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
