[PATCH tip/core/rcu 03/52] rcu: Remove rsp parameter from rcu_report_unblock_qs_rnp()

From: Paul E. McKenney
Date: Wed Aug 29 2018 - 18:44:05 EST


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_report_unblock_qs_rnp(), which is particularly appropriate in
this case given that this parameter is no longer used.
