From 4b12db939166042eb78e592bdf94ef113c14e379 Mon Sep 17 00:00:00 2001 From: Mathieu Poirier Date: Tue, 24 Jan 2017 14:11:35 -0700 Subject: [PATCH] sched/core: Fix &rd->cpudl memory leak While in the process of initialising a root domain, if function cpupri_init() fails the memory allocated in cpudl_init() is not reclaimed. Adding a new goto target to cleanup the previous initialistion of the root_domain's dl_bw structure reclaims said memory.
