From 22da956953f371c1ee7a578c31ed8c5702cb52b1 Mon Sep 17 00:00:00 2001 From: Viresh Kumar Date: Tue, 4 Jun 2013 15:41:15 +0530 Subject: [PATCH] sched: Optimize build_sched_domains() for saving first SD node for a cpu We are saving first scheduling domain for a cpu in build_sched_domains() by iterating over the nested sd->child list. We don't actually need to do it this way. tl will be equal to sched_domain_topology for the first iteration and so we can set *per_cpu_ptr(d.sd, i) based on that. So, save pointer to first SD while running the iteration loop over tl's.
