Struct NvRmControlParams 

#[repr(C)]
struct NvRmControlParams {
    h_client: u32,
    h_object: u32,
    cmd: u32,
    flags: u32,
    params: u64,
    params_size: u32,
    status: u32,
}

The param block the RM control ioctl hands back (NVOS54_PARAMETERS, 32 bytes, pointed at by arg) — modeled here so the filter can identify and validate an enumeration call before it touches the GPU-id array it carries.

The rewrite reads cmd to identify the enumeration API, status and params to confirm the call succeeded and carries a payload, and params_size to validate the exact payload layout before dereferencing params (a u64 user pointer to the command-specific struct).
