Subject[PATCH tip/core/rcu 27/52] rcu: Remove rsp parameter from rcu_check_gp_start_stall()
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_check_gp_start_stall().
