129  state等于Must be an lvalue. Since @var must be a simple identifier,* we force a syntax error here if it isn't.(net_rand_state)
131  prandom_bytes_state - get the requested number of pseudo-random bytes*@state: pointer to state structure holding seeded state.*@buf: where to copy the pseudo-random bytes to*@bytes: the requested number of bytes
132  The weird & is necessary because sparse considers (void)(var) to be* a direct dereference of percpu variable (var).(net_rand_state)
