    Subject[PATCH tip/core/rcu 14/52] rcu: Remove rsp parameter from rcu_future_gp_cleanup()
    Date
    There now is only one rcu_state structure in a given build of the
    Linux kernel, so there is no need to pass it as a parameter to RCU's
    functions. This commit therefore removes the rsp parameter from
    rcu_future_gp_cleanup().
