David Tolnay 4b292afafc clippy: Resolve cast_ptr_alignment ... This CL fixes four cases of what I believe are undefined behavior: - In vhost where the original code allocates a Vec<u8> with 1-byte alignment and casts the Vec's data pointer to a &mut vhost_memory which is required to be 8-byte aligned. Underaligned references of type &T or &mut T are always undefined behavior in Rust. - Same pattern in x86_64. - Same pattern in plugin::vcpu. - Code in crosvm_plugin that dereferences a potentially underaligned pointer. This is always undefined behavior in Rust.
