preempt_disable() is a no-op when !CONFIG_PREEMPT_COUNT, right?

[lkp-developer] [sched/fair] 4e5160766f: +149% ftq.noise.50% regression
by kernel test robot
Greeting,
FYI, we noticed a 149% regression of ftq.noise.50% due to commit:
commit: 4e5160766fcc9f41bbd38bac11f92dce993644aa ("sched/fair: Propagate asynchrous detach")
https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git master
in testcase: ftq
on test machine: 8 threads Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz with 8G memory
with following parameters:
nr_task: 100%
samples: 6000ss
test: cache
freq: 20
cpufreq_governor: powersave
test-description: The FTQ benchmarks measure hardware and software interference or 'noise' on a node from the applications perspective.
test-url: https://github.com/rminnich/ftq
In addition to that, the commit also has significant impact on the following tests:

[PATCH 0/4] lkp: add initial opensuse support
by Luis R. Rodriguez
I received a failed test results notice from 0-day LKP test suite
using trinity, however it was pretty hard to get reproduce given
the LKP did not have OpenSUSE support to start off with, but the
second issue I've stubmled upon is beyond me -- running either:
./bin/lkp qemu -k ~mcgrof/linux-next/arch/x86/boot/bzImage job-script
or
lkp qemu jobs/trinity.yaml
ends up creating calling a few subroutines or files which are
clearly not present, then tries to create a cpio archive but
clearly there are a few files which LKP tree expects you to have
and are not present such as lkp and lkp/scheduled.
This is a run on OpenSUSE, first we install the dependencies for
trinity.yaml deps:
# lkp install jobs/trinity.yaml
Then we try to run it:
# lkp qemu jobs/trinity.yaml
jobs/trinity.yaml: line 1: suite:: command not found
jobs/trinity.yaml: line 2: testcase:: command not found
jobs/trinity.yaml: line 4: runtime:: command not found
jobs/trinity.yaml: line 6: kmsg:: command not found
jobs/trinity.yaml: line 7: rootfs:: command not found
jobs/trinity.yaml: line 9: trinity:: command not found
make: Entering directory '/home/mcgrof/devel/lkp-tests/bin/event'
klcc -c -o wakeup.o wakeup.c
klcc -static -o wakeup wakeup.o
rm -f wakeup.o
strip wakeup
make: Leaving directory '/home/mcgrof/devel/lkp-tests/bin/event'
cpio: lkp: Cannot stat: No such file or directory
cpio: lkp/scheduled: Cannot stat: No such file or directory
cpio: blank line ignored
cpio: File /dev/mqueue/���� shrunk by 20 bytes, padding with zeros
This never complets, it just sits there.
Either way these patches help start to add OpenSUSE support.

[lkp] [x86/acpi] dc6db24d24: BUG: unable to handle kernel paging request at 0000116007090008
by kernel test robot
FYI, we noticed the following commit:
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master
commit dc6db24d2476cd09c0ecf2b8d80313539f737a89 ("x86/acpi: Set persistent cpuid <-> nodeid mapping when booting")
in testcase: vm-scalability
with following parameters:
runtime: 300
thp_enabled: never
thp_defrag: never
nr_task: 1
nr_pmem: 1
test: swap-w-rand
cpufreq_governor: performance
The motivation behind this suite is to exercise functions and regions of the mm/ of the Linux kernel which are of interest to us.
on test machine: 72 threads Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz with 128G memory

commit 659cf9f5824a12e6b50785e4e9cf1adf8a3adbd0
Author: Nicolai Hähnle <Nicolai.Haehnle(a)amd.com>
AuthorDate: Wed Dec 21 19:46:36 2016 +0100

locking/ww_mutex: Optimize ww-mutexes by waking at most one waiter for backoff when acquiring the lock
The wait list is sorted by stamp order, and the only waiting task that may
have to back off is the first waiter with a context.
The regular slow path does not have to wake any other tasks at all, since
all other waiters that would have to back off were either woken up when
the waiter was added to the list, or detected the condition before they
added themselves.

[of/unittest] 815d74b35e: BUG: unable to handle kernel NULL pointer dereference at 00000012

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git master

CommitDate: Thu Mar 3 16:51:31 2016 -0600
of/unittest: fix infinite loop in of_unittest_destroy_tracked_overlays()
of_overlay_destroy() can return `-ENODEV' error code once it
failed to find the requested overlay in `ov_idr'. However,
of_unittest_destroy_tracked_overlays() does not handle this
error code correctly and continues to call of_overlay_destroy()
on the 'missing' overlay over and over again. This results in
a printk flood
[..]

[..]
which is not really good due to printk design, and can lead to soft
lockups, hard lockups, etc. (depending on the context console_unlock()
is being called from). The problem has bee observed in real life
and reported by Ying Huang.
This patch does not address the root cause of missing overlay in
`ov_idr', it fixes the endless loop only.
