rcu: Mark rcu_state.gp_seq to detect concurrent writes The rcu_state structure's gp_seq field is only to be modified by the RCU grace-period kthread, which is single-threaded. This commit therefore enlists KCSAN's help in enforcing this restriction. Signed-off-by: Paul E. McKenney <paulmck@kernel.org>
