From ea12ff2b7d97607bb69b50ccc30d3819b44ffb2b Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Tue, 3 Jul 2018 17:22:34 -0700 Subject: [PATCH] rcu: Remove rsp parameter from check_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 check_cpu_stall(). Signed-off-by: Paul E.
