From 4aa846f97c0c0d9740d120f9ac3e2fba1522ac0c Mon Sep 17 00:00:00 2001 From: "Paul E. McKenney" Date: Thu, 29 Jul 2021 20:30:32 -0700 Subject: [PATCH] rcu: Make rcutree_dying_cpu() use its "cpu" parameter The CPU-hotplug functions take a "cpu" parameter, but rcutree_dying_cpu() ignores it in favor of this_cpu_ptr(). This works at the moment, but it would be better to be consistent. This might also work better given some possible future changes. This commit therefore uses per_cpu_ptr() to avoid ignoring the rcutree_dying_cpu() function's argument. Signed-off-by: Paul E.
