Subject: [PATCH v2 01/10] cyrpto/b128ops: Remove struct u128
References: <20230202145030.223740842@infradead.org>
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Precedence: bulk

Per git-grep u128_xor() and its related struct u128 are unused except
to implement {be,le}128_xor(). Remove them to free up the namespace.
