6017 * register_ftrace_direct - Call a custom trampoline directly
6018 * for multiple functions registered in @ops
6019 * @ops: The address of the struct ftrace_ops object
6020 * @addr: The address of the trampoline to call at @ops functions
6021 *
6022 * This is used to connect a direct calls to @addr from the nop locations
6023 * of the functions registered in @ops (with by ftrace_set_filter_ip
6024 * function).
6025 *
6026 * The location that it calls (@addr) must be able to handle a direct call,
6027 * and save the parameters of the function being traced, and restore them
6028 * (or inject new ones if needed), before returning.
6029 *
6030 * Returns:
6031 * 0 on success
6032 * -EINVAL - The @ops object was already registered with this call or
6033 * when there are no functions in @ops object.
6034 * -EBUSY - Another direct function is already attached (there can be only one)
6035 * -ENODEV - @ip does not point to a ftrace nop location (or not supported)
6036 * -ENOMEM - There was an allocation failure.
