Subject[PATCH tip/core/rcu 04/52] rcu: Remove rsp parameter from rcu_report_qs_rdp()
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_report_qs_rdp().
