From a1bd06853ee478d37fae9435c5521e301de94c67 Mon Sep 17 00:00:00 2001 From: Phil Auld Date: Wed, 5 Aug 2020 16:31:38 -0400 Subject: [PATCH] sched: Fix use of count for nr_running tracepoint The count field is meant to tell if an update to nr_running is an add or a subtract. Make it do so by adding the missing minus sign.
