McKenney" <paulmck@...ux.vnet.ibm.com> Subject: [PATCH tip/core/rcu 11/52] rcu: Remove rsp parameter from print_other_cpu_stall() 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(). Signed-off-by: Paul E.
