commit 922c7b406473a362269dae9d1a1a1c65e23368c7
Author: Sebastian Andrzej Siewior <bigeasy(a)linutronix.de>

locking/mutex: Test for initialized mutex
An uninitialized/ zeroed mutex will go unnoticed because there is no
check for it. There is a magic check in the unlock's slowpath path which
might go unnoticed if the unlock happens in the fastpath.
Add a ->magic check early in the mutex_lock() and mutex_trylock() path.

[sched/fair] d2a99d2651: reaim.jobs_per_min -2.3% regression
by kernel test robot
Greeting,
FYI, we noticed a -2.3% regression of reaim.jobs_per_min due to commit:
commit: d2a99d26519c181c5101e25d47ef8917fa0466d0 ("sched/fair: rework load_balance")
https://git.linaro.org/people/vincent.guittot/kernel.git sched-rework-load_balance
in testcase: reaim
on test machine: 40 threads Skylake-SP with 64G memory
with following parameters:
runtime: 300s
nr_task: 100%
test: alltests
cpufreq_governor: performance
test-description: REAIM is an updated and improved version of AIM 7 benchmark.
test-url: https://sourceforge.net/projects/re-aim-7/
Details are as below:

Correct.

Yes. That fixes it and works as expected. Thanks for the quick
resolution. I surely stared at that function, but was not sure how to fix
