From 8ea9183db4ad8afbcb7089a77c23eaf965b0cacd Mon Sep 17 00:00:00 2001 From: Vincent Guittot Date: Tue, 19 Oct 2021 14:35:37 +0200 Subject: sched/fair: Cleanup newidle_balance update_next_balance() uses sd->last_balance which is not modified by load_balance() so we can merge the 2 calls in one place.
