by kernel test robot
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://internal_mailing_list_patch_tree Oleg-Nesterov/Was-sched-start-stopper-early
commit 51785b72f86aa310dc063fda129e1ef716a62599
Author: Oleg Nesterov <oleg(a)redhat.com>
AuthorDate: Sat Oct 10 20:53:09 2015 +0200
Commit: 0day robot <fengguang.wu(a)intel.com>
CommitDate: Sun Oct 11 08:04:28 2015 +0800
sched: select_task_rq() should check cpu_active() like select_fallback_rq()
I do not understand the cpu_active() check in select_fallback_rq().
x86 doesn't need it, and the recent commit dd9d3843755d "sched: Fix
cpu_active_mask/cpu_online_mask race" documents the fact that on any
architecture we can ignore !active starting from CPU_ONLINE stage.
But any possible reason why do we need this check in "fallback" must
equally apply to select_task_rq().
