Subject[PATCH tip/core/rcu 11/52] rcu: Remove rsp parameter from print_other_cpu_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
print_other_cpu_stall().
