From a0b8c6af29a4be3ca2ff9a95cf71e54db5d73e65 Mon Sep 17 00:00:00 2001 From: "Dr. David Alan Gilbert" Date: Fri, 24 Oct 2025 21:51:20 +0100 Subject: lib/xxhash: remove more unused xxh functions xxh32_reset() and xxh32_copy_state() are unused, and with those gone, the xxh32_state struct is also unused. xxh64_copy_state() is also unused. Remove them all. (Also fixes a comment above the xxh64_state that referred to it as xxh32_state).
